description: Ausgangspunkt der vorliegenden Arbeit ist die aus den Defiziten starr verketteter Fließmontagelinien resultierende Forderung nach veränderungsfähigen Systemen für die zukünftige Automobilmontage. Als Ausprägungsform eines veränderungsfähigen Systems grenzt die fluide Montage, die im Kontext des Forschungscampus ARENA2036 erarbeitet wird und über eine spezifische Anzahl an Freiheitsgraden verfügt, den Untersuchungsbereich dieser Arbeit ab. Es zeigt sich, dass in dieser Umgebung die Gewährleistung der kurzfristigen Materialverfügbarkeit infolge dynamischer Materialflussstrukturen eine besondere Herausforderung darstellt. Aus diesem Grund beschäftigt sich die vorliegende Arbeit mit der übergeordneten Forschungsfrage, wie sich die Materialverfügbarkeit während des Betriebs eines fluiden Montagesystems sicherstellen lässt. Als konkreter Handlungsbedarf wird die Entwicklung und Untersuchung einer Methodik zur Überprüfung und Sicherstellung der Materialverfügbarkeit in fluiden Montagesystemen identifiziert. Die entwickelte Methodik setzt sich aus vier aufeinanderfolgenden Prozessschritten zusammen. Hierbei handelt es sich um die Schritte Initialisierung, Zielsuche und Aufgabenableitung, Lösungssuche sowie Lösungsauswahl. Die Methodik ist als Bestandteil des Materialbereitstellungssystems dem Aufgabenfeld der Logistik zugeordnet und trägt zur Koordination des Montage- und Materialbereitstellungssystems bei, da sie an der Schnittstelle dieser beiden Systeme eingesetzt wird. Die simulationsbasierte Untersuchung der Methodik erfolgt am Beispiel einer Cockpit-Vormontage. Verschiedene Experimente werden durchgeführt, um die Funktionsweise der Methodik zu erproben und den Einfluss verschiedener Größen auf die Materialverfügbarkeit zu analysieren. Wie die Simulationsergebnisse zeigen, gelingt es durch den Einsatz der Methodik, die Materialverfügbarkeit in fluiden Montagesystemen während des laufenden Betriebs sicherzustellen. Hierbei hat sich insbesondere die Verwendung des Ansatzes zur logistik- und montageinduzierten Materialverfügbarkeit als förderlich erwiesen. Dadurch leistet die vorliegende Arbeit einen Beitrag zur Ausgestaltung der Materialbereitstellung in fluiden Montagesystemen.

Magnetoresistance and Associated Effects (Virtual)
Recently, we have developed the SOT-MTJ-compatible Co20Fe60B20/W/Co20Fe60B20 “T-type” magnetic trilayers, where the upper CoFeB layer has perpendicular magnetic anisotropy (PMA) and the bottom CoFeB has in-plane magnetic anisotropy (IMA).We can realize field-free switching in a series of samples whose interlayer coupling field can be tuned from 20 Oe to 255 Oe through changing the thicknesses of W interlayer, a sizeable value for assisting SOT switching of PMA materials. The anisotropic field Hk of this “T-type” system is about 13.9 kOe, which is well suited for magnetic storage and scaling down devices. Meanwhile, this system verifies the possibility of SOT switching using ferromagnetic metals as a spin source and the spin hall angle of this system is: |θSH| = 0.149, considerable for write efficiency. Finally, we tested the SOT-switching probability of this PMA system and we found that it can implement the function of probability-adjustable true random number generator (TRNG) in principle. We think this “T-type” system will play an important role in the future of low-power, non-volatile, multifunctional logic integrated circuits.References: [1] Ma, Tianyi, Wan, Caihua, Dong, Jing, Physical Review B 101(13): 134417(2020) [2] Yang, Yumeng, Xie, Hang, Xu, Yanjun, Physical Review Applied 13, 034072 (2020) [3] Grimaldi, E., Krizakova, V., Sala, G., Nat Nanotechnol 15(2): 111-117 ( (2020)) [4] Kim, J., Sinha, J., Hayashi, M., Nat Mater 12(3): 240-245 (2013) [5] Lau, Y.

description: This essay looks at how Herbert Warnke, 1948–1975 chairman of the federale executive board FDGB and member of the SED- (Socialist Unity Party of Germany) leadership, thought and behaved in the political scenery of the German Democratic Republic (GDR) and how he understood his own role. The article focuses on the divergence between individuality and communist party-discipline. Another problem is the applicability of idea “elite” for the FDGB-leadership. Answer upon this is abiding ambiguous. Warnke’s politcal career was exemplary referring to this: Party-discipline on the one hand, and frequently to run withdrawal in private life otherwise.

description: We propose VQE circuit fabrics with advantageous properties for the simulation of strongly correlated ground and excited states of molecules and materials under the Jordan-Wigner mapping that can be implemented linearly locally and preserve all relevant quantum numbers: the number of spin up ($α$) and down ($β$) electrons and the total spin squared. We demonstrate that our entangler circuits are expressive already at low depth and parameter count, appear to become universal, and may be trainable without having to cross regions of vanishing gradient, when the number of parameters becomes sufficiently large and when these parameters are suitably initialized. One particularly appealing construction achieves this with just orbital rotations and pair exchange gates. We derive optimal four-term parameter shift rules for and provide explicit decompositions of our quantum number preserving gates and perform numerical demonstrations on highly correlated molecules on up to 20 qubits.

VP2-01: Numerical analysis of write-error-rate in magnetic-topological-insulator-based devices with voltagecontrolled magnetization switching

Fundamental Properties and Cooperative Phenomena (Virtual)
Electrical control of magnetization has attracted much attention for next generation spintronic devices such as non-volatile magnetic memory, high-speed logic, and low-power data transmission. Voltage-controlled magnetization anisotropy (VCMA) is a promising way to drive magnetization switching with high energy efficiency. Recently, we proposed the magnetic topological-insulator(MTI)-based device with field-effect-transistor (FET)-like structrure[1]. It was reported clear magnetization switching by combining adequate source-drain voltage and gate pulse with low writing energy of less-than 0.1fJ/bit. Although the gate pulse shape and the signal-to-noise ratio affect the write-error-rate(WER) by peripheral electrical circuits in the practical application, WER in the MTI device has not been discussed yet. In this study, we demonstrate magnetization switching in the MTI devices under external disturbance such as electrical circuit noise and thermal fluctuation by the micromagnetic simulation. Figure 1 illustrates a MTI-based device involving a MTI film as in which the top of the surface of MTI is a conduction-channel layer. This device realizes magnetization switching via spin-orbit torque (SOT) and voltage-controlled magnetic anisotropy (VCMA) which originate from 2D-Dirac electronic structure without external bias. From the numerical calculation, we reveal that the device operation is extremely robust against circuit delay and signal-to-noise ratio. Figure 2 shows WER as a function of temperature T. The device size L of 100 nm was used. We demonstrate that the WER on the order of approximately 10−4 or below is achieved around room temperature due to steep change in VCMA. Also, we show that the larger SOT improves thermal stability factor. This study provides a new perspective for developing voltage-driven spintronic devices with ultra-low power consumption.References: [1] T. Chiba and T. Komine, Phys. Rev. Appl. 14, 034031 (2020).

description: In this article Stefan Remeke analyses the sociopolitical elite of the ‘Federation of German Trade Unions’ (Deutscher Gewerkschaftsbund/DGB) in the time of reforms of the socioliberal coalition, considering Gerd Muhr and Maria Weber as examples. From 1969 to 1990 Muhr was deputy chairman of the DGB as well as Weber. She, as head of the christian-social movement in the DGB was member of the board from 1972 to 1982. Both decided about crucial key positions in the social policy of the German trade unions over a long period of time. Borsdorf ’s category of the “Gewerkschaftsmanager” will be applied on Muhr (SPD, member in the sociopolitical commission of the SPD) and Weber (CDU/CDA, chairperson of the CDA). The two acted as intermediaries between trade unions and parties (“Manager der politischen Beeinflussung”) and between the DGB and its particular members (“Manager der einheitsgewerkschaftlichen Partikularinteressen”). This interrelation will be presented in a comparative, biographical way.

Multi-Functional Magnetic Materials and Applications (Virtual)
Elemental doping and/or alloying of light elements to ordinary metallic compounds have attracted attention in the field of recent spintronic materials.[1] For example, carbon greatly boosts the anomalous Hall conductivity of CoMn thin films [2], and boron modulates the spin structures and inter-band optical transitions of the host Mn4N thin films [3] In order to explore the impact of nitrogen on charge-to-spin conversion efficiency, in this study we compared the spin-Hall angle (SHA) evaluated in the existing Mn3Pt/CoFeB[4,5] and Mn3PtN/CoFeB bilayer systems, which has not been reported to date. The Mn3PtN compound is predicted to be one of the non-collinear antiferromagnets with Berry curvatures from Weyl points near the Fermi level,[6] promising large anomalous Hall conductivity. The multilayered samples with Mn3PtN (t=5,7,10 nm)/CoFeB (3nm)/MgO (3nm) were deposited on MgO (001) substrates using the DC/RF magnetron sputtering systems. Figure 1 shows the Vmix line shape in the spin-orbit torque ferromagnetic resonance (ST-FMR) at fixed RF frequency 7 GHz, by scanning the in-plane dc external magnetic field Hext at angle φ (typically 45○). Figure 2 significantly represents the thickness-dependent spin Hall angle, we observed a significant ten-fold higher SHA, which surpasses the performance of the controlled Mn3Pt/CoFeB samples; therefore, the presence of N2 would lead to higher efficient charge-to-spin conversion. While the strength of the damping-like field of the epitaxial samples is greater than that of the controlled Mn3Pt/CoFeB samples, determined by the second harmonic Hall measurement provides qualitative support for the ST-FMR conclusion. One of the possible origins for the enhancement of SHA could be the electronic structures induced by the presence of nitrogen. In addition, the influences of crystal structures and surface morphologies on SHA will be discussed at the conference.References: [1] Shinji Isogami and Yukiko K. Takahashi, Adv. Electron.

Magnetization Dynamics III: Micromagnetics and Modeling
Magnetic materials at the nanoscale have attracted considerable interest both from academia and industry. A key aspect is the thorough understanding of the emerging magnetization field configurations, and their behaviour within samples and devices. However, an in-depth study such as plotting a magnetic phase diagram [1, 2] as a function of geometry, material parameter or applied field, can lead to creation of a large amount of data. Its evaluation typically requires considerable human effort and time. We report that it is possible to automate this process, to a certain degree, using an unsupervised machine learning (ML) algorithm. In this study, we use Agglomerative Clustering in magnetic phase diagram discovery of a FeGe disc with changing external magnetic field. First, we obtain the equilibrium magnetisation configurations by changing the field values from 0 to 1.2 T using micromagnetic simulations. Second, we obtain a feature space by passing the simulation data through the pre-trained layers of VGG-16 [3]. As the final step, we perform the Agglomerative Clustering on the feature space to sort the configurations in different classes. We find that the algorithm performs well when compared to the published results [1] on the same material geometry and range of external fields (Fig. 1). Although, the different classes obtained through the process do show some mixing of the equilibrium magnetisation configurations (Fig. 2). Our study shows that ML can be used to aid researchers in evaluating large amounts of magnetisation data. In our case, the algorithm clustered a thousand simulation results into individual classes without any training or human supervision, greatly reducing human effort for the task.References: [1] M.

VP2-08: Study of Spin Glass State in Co doped NdMnO3

Fundamental Properties IV: 2D and Topological Materials
The spin glass (SG) behaviour in NdMn0.6Co0.4O3 has been studied using temperature dependent ac susceptibility measurement of in-phase (χ`ac ) and out of phase component (χac``) . The measurement was performed in an ac field of 4 Oe and 0 Oe dc field at frequencies of 111 Hz, 311 Hz, 1011 Hz, and 1311 Hz. The peak position in χ`ac, corresponding to Tf , moves towards higher temperatures with it’s magnitude decreasing as the frequency increases. This is a strong indication of the existence of SG state and absence of long range feromagnetic (FM) ordering. Temperature variation for out of phase component or imaginary part of ac susceptibility χac`` at different frequencies is just opposite to χac` and agrees with the existence of SG state. The parameter called relative shift in freezing temperature (δTf) per decade of frequency on a logarithmic scale is a handy tool to distinguish between different SG systems. It’s value for the sample under study is found to be δTf = 0.0089 which agrees with the one reported for canonical SG systems [1,2]. In order to confirm the existence of canonical SG state in the NdMn0.6Co0.4O3 sample the ac susceptibility data was further analyzed using Arrhenius, Vogel Fulcher, and Power –law. Using Arrhenius law the relaxation time τ0 of a single spin flip of the fluctuating entities was found to be τ0∼10-122 s and the barrier height Ea /kB = 37407, these are quite unrealistic values thus ruling out the existence of superparamagnetic state in NdMn0.6Co0.4O3. The value of τ0 obtained using Vogel Fulcher and Power –law is of the order of ~ 10-13 s which is distinctive value of canonical SG system. Further, the value of zν` ~7 for the sample under study, where z is the dynamical exponent and ν` is the critical exponent of the spin correlation length. For canonical SG system zν` lies in the range of 4 -12. The criterion introduced by Tholence [3] δTTh = (Tf - T0)/Tf is used to compare different SG systems. As per this criterion, the value of δTTh obtained for NdMn0.6Co0.4O3 ~0.07 which are one order of magnitude less than the values reported for clsuter glass state [1]. These values are comparable to those obtained for canonical SG system like CuMn [3].References: 1. J. A. Mydosh, Spin Glasses: An Experimental Introduction (1993). 2. N. Khan, A. Midya, P.

He belonged to the few working class leaders who fundamentally looked into fascism, capitalism and democracy in the Federal Republic of Germany. Cold War and the restorative socio-political climate of the fifties and sixties encouraged Brenner to claim that German society should work up the faults made in the past and fight against authoritarian tendencies in state and society. Under certain circumstances, Brenner considered conceivable not a recurrence of the Nazi regime, but a deformation or even destruction of democracy. To avoid this, Brenner regarded as one of the most important missions of the labour movement.

Orbitronics: From Orbital Currents Created by Charge Currents to Creation by Light or RF Excitation
Recent progress in orbitronics reveals the possibility of using orbit current as an information carrier. Several recent works have highlighted the importance of the orbital degree of freedom in condensed matter physics and kicked off the emergent research field of orbitronics [1]. Orbitronics exploits the transport of orbital angular momentum through materials by orbit currents which can be exploited as an information carrier in solid-state devices. As for the conversion between spin and charge current by SHE or SREE, it has been theoretically predicted and experimentally shown that a charge current can be converted into an orbit current via the orbital Hall effect (OHE) or the orbital Rashba-Edelstein effect (OREE) [2–4]. THz emission from magnetic heterostructures offers a unique opportunity for studying the orbital effects [5]. Here we show that orbital currents can be created by femtosecond light pulses on Ni layers and then converted to charge current pulses for the emission of terahertz pulses. Based on the new experimental method, we study the production of light-induced orbit current and their exploitation for terahertz emission from NM/Ni bilayers with NM = Cu, Ta or Pt. We find terahertz emission of the same polarity with Cu, Ta, and Pt as NM in NM/Ni bilayers despite the opposite SHE of Ta with respect to Pt (this common polarity is also opposite to the polarity of the AHE-induced emission by a Ni monolayer). We ascribe these results to an efficient light-induced emission of orbit currents in Ni, and we have presented a detailed analysis of them in the simpler situation of Cu/Ni from which, in addition, we can extract information on the velocity and orbital flip time of the orbit carriers. The main general results are that orbit currents can be generated not only by conversion from charge or spin currents but also induced by light. In THz emission experiments, the analysis of the emission delays can bring precious information on the dynamics of the orbit carriers. All these results open new routes for developing future devices using orbit currents.References: [1] D. Go, D. Jo, H.-W. Lee, et al., Europhys. Lett. 135, 37001 (2021). [2] D. Go, D. Jo, T.

Born in Köln 1886 and from the beginning of his work, he was a member of the catholic labour movement and till 1933 he was a secretary in the board of the christian metalworkers trade union. After the World War he was a “fighter” for the unified trade union even against his own party the CDU. At the founding congress of the DGB 1949 in Munich he was elect as vice chairman onto the board of the DGB. From 1949 till 1956 he was the vice chairman and even representative of that trade unionists, who where also member of the CDU.

Search for suitable magnetic material for use as refrigerant at low temperatures assumes immense importance for realization of magnetic refrigeration-based hydrogen and helium liquefaction [1]. In the present work, magnetic and magnetocaloric properties of polycrystalline Gd3Co4Ge13 (Cubic Yb3Rh4Sn13-type, space group Pm-3n, N 223, cP40) have been studied by dc magnetization measurements in fields up to 140 kOe. The compound Gd3Co4Ge13 undergoes antiferromagnetic-like transition at 9 K (TN) [Fig. 1a]. The antiferromagnetism appears to be weak and in applied magnetic fields larger than 40 kOe, ferromagnetic interactions become prevalent. This is evident via the field-induced cross-over from the antiferromagnetic to ferromagnetic state that is marked as a change from inverse to normal magnetocaloric effect in the isothermal magnetic entropy change vs temperature plot around the antiferromagnetic transition temperature. At 2 K, the sample shows S-type behaviour with a tendency towards saturation. A magnetic moment of 5.3 µB/ per Gd3+ is obtained in 140 kOe field. The maximum isothermal magnetic entropy change at 8 K is -1.56 J/kg×K for a field change of 50 kOe and the corresponding relative cooling power is 34 J/kg. The isothermal magnetic entropy change shows a linear increase for magnetic field changes larger than 40 kOe [Fig. 1b].References: [1.] Wei Liu, Eduard Bykov, Sergey Taskaev, Mikhail Bogush, Vladimir Khovaylo, Nuno Fortunato, Alex Aubert, Hongbin Zhang, Tino Gottschall, Jochen Wosnitza, Franziska Scheibel, Konstantin Skokov and Oliver Gutfleisch, “A study on rare-earth Laves phases for magnetocaloric liquefaction of hydrogen”, Appl.

description: Through an evaluation of the rise and fall of the high ranking communist and trade union leader, Willi Agatz, this essay tries to shed light on the process of trade union integration after fascism. Agatz work was characterized by the initially successful attempt to reconcile a program of social revolution with day-to day union business. However, in the face of political polarization at the end of the 1940s Agatz position within the IV Bergbau became increasingly precarious. His refusal to renounce communist politics ultimately let to his expulsion from the union. All in all, his work as a TU secretary had a paradoxically effect. In fostering the integration of important groups of radical miners into the Trade Union organization he involuntarily helped to weaken the communist movement in the pit fields, the basis of his own power within the Union.

The limit processes are generalised Wiener processes. The obtained convergence is in space-time, finite-dimensional distributions sense.

The EWP (Electric Water Pump) motor for automobiles is a very important element in the cooling system of automobiles. This is because it must have high output within a limited volume to circulate the cooling water and maintain a constant temperature. In the limited space of automobiles, the advantages of miniaturization and increase in power density are very great. In this paper, we propose an improved EWP motor for automobiles by reducing the axial size of the motor and increasing the radial size to take the form of a thin structure and increasing the power density to secure a spatial advantage. When replacing an existing radial permanent magnet motor with an axial flux motor, the torque density in the same volume is proportional to the cube of the motor diameter, resulting in higher electromagnetic torque and higher torque density. In the multi-pole multi-slot structure, the thickness of the backyoke of the stator and rotor can be reduced. However, considering the volume of EWP motors, which are small motors, the number of winding turns decreases in the multi-slot structure, and the rate of leakage without linking magnetic flux to the stator increases in the multi-pole structure. In addition, if the number of poles increases, the yoke thickness can be reduced, but the mechanical strength can be lowered. Therefore, a 10-pole 12-slot structure was selected. As above, the design goal of Axial Flux Motor with small size and short axial length is that the backyoke core is saturated and performance has not deteriorated, and that as many windings as possible can be wound on the slot within a small size. Therefore, the rotor core thickness, slot width, and axial length were set as design variables. The proportional relationship between the output value according to the change of each design variable and the number of turns per tooth was confirmed, and even if the target output was satisfied, the model in which the core part was excessively saturated was excluded. Through this process, the optimal model was derived, and the volume increased by about 9% compared to the existing model, but the output increased by about 84%, confirming that the power density increased.References: [1] A.

description: We present new observational results obtained for the Galactic non-thermal radio source G328.4+0.2 to determine both if this source is a pulsar wind nebula or supernova remnant, and in either case, the physical properties of this source. Using X-ray data obtained by XMM, we confirm that the X-ray emission from this source is heavily absorbed and has a spectrum best fit by a power law model of photon index=2 with no evidence for a thermal component, the X-ray emission from G328.4+0.2 comes from a region significantly smaller than the radio emission, and that the X-ray and radio emission are significantly offset from each other. We also present the results of a new high resolution (7 arcseconds) 1.4 GHz image of G328.4+0.2 obtained using the Australia Telescope Compact Array, and a deep search for radio pulsations using the Parkes Radio Telescope. We find that the radio emission has a flat spectrum, though some areas along the eastern edge of G328.4+0.2 have a steeper radio spectral index of ~-0.3. Additionally, we obtain a luminosity limit of the central pulsar of L_{1400} < 30 mJy kpc^2, assuming a distance of 17 kpc. In light of these observational results, we test if G328.4+0.2 is a pulsar wind nebula (PWN) or a large PWN inside a supernova remnant (SNR) using a simple hydrodynamic model for the evolution of a PWN inside a SNR. As a result of this analysis, we conclude that G328.4+0.2 is a young (< 10000 years old) pulsar wind nebula formed by a low magnetic field (<10^12 G) neutron star born spinning rapidly (<10 ms) expanding into an undetected SNR formed by an energetic (>10^51 ergs), low ejecta mass (M < 5 Solar Masses) supernova explosion which occurred in a low density (n~0.03 cm^{-3}) environment.

Magneto-Caloric Materials and Devices
Magnetic materials with a large magnetocaloric effect (MCE) have attracted attention owing to their potential application to highly efficient and environmentally friendly magnetic refrigeration. Because Laves compounds RT2 (R = Gd-Yb, T = Al, Ni, Co) exhibit large MCEs associated with a magnetic transition occurring in the temperature range between the two liquefaction temperatures of hydrogen and nitrogen [1,2], which are expected to be used in magnetic refrigeration to liquefy hydrogen [3]. Processing magnetocaloric bulk materials into magnetic refrigerant particles is an essential for developing magnetic refrigerators. However, the effect of the quenching during particle fabrication on the material properties has not been investigated in detail. In this work, the effect of the quenching process and post-annealing on the magnetic, magnetocaloric and crystallographic properties in gas-atomized particles of the ErCo2 and HoAl2 was investigated. The results demonstrate that the physical properties of ErCo2 are significantly changed by quenching process and post-annealing. Changing the annealing conditions of the quenched ErCo2 particles can change the magnetic transition temperature, and the order of the magnetic phase transition from a second-order to a first-order (Fig. 1). Moreover, a strong correlation is observed between the Curie temperature and the lattice constant, suggesting the importance of the magneto-structural coupling. As the particles anneal progress, they develop a giant magnetic entropy change due to the change from a second-order to a first-order transition (Fig. 2). In HoAl2 compound, no significant changes in magnetic and magnetocaloric properties between the quenched particle and annealed one were observed (not shown), even though ErCo2 and HoAl2 are the same Laves compounds. In this presentation, we will show the differences of the detailed properties between the ErCo2 and HoAl2 compounds and discuss possible mechanism.

Raumbildung als ökonomischer, sozialer und mentaler Prozess

description: This article shortly describes recent approaches to a renewed analysis of space (“spatial turn”) in German historiography and historical geography. It is shown that a new perception of historical space already accompanied the revival of the history of industrial regions since the 1960s (Regionalgeschichte instead of Landesgeschichte). Following Simmel, a perception of historical space as condensation of communications would make it possible to distinguish different capacities to communicate within different classes of a given society. Thus, migrant societies such as the ones that evolved from economic growth in heavy industrial regions everywhere in Europe would display a rather low capacity to construct mind space and regional identity on their own, whereas in the same regions, the middle classes developed rather poorly, so that mind space construction rested on weak shoulders. It is therefore that regional identity construction within formerly heavy industrial regions sprang off from structural change and educational reform mostly in the 1960s.

Da auch die Aufkommen an Altfetten bei lokalen Sammlern zu finden sind, empfiehlt sich eine dezentrale Aufbereitung und Weiterverarbeitung in absätzig arbeitenden, dezentralen Kleinanlagen. Zur weiteren Vermeidung von Transportaufkommen, sollte der Absatz des Kraftstoffes im Einzugsbereich der Anlage liegen.

Three Particle Correlations from STAR

description: Two-particle correlations have shown modification to the away-side shape in central Au+Au collisions relative to $pp$, d+Au and peripheral Au+Au collisions. Different scenarios can explain this modification including: large angle gluon radiation, jets deflected by transverse flow, path length dependent energy loss, Cerenkov gluon radiation of fast moving particles, and conical flow generated by hydrodynamic Mach-cone shock-waves. Three-particle correlations have the power to distinguish the scenarios with conical emission, conical flow and Cerenkov radiation, from other scenarios. In addition, the dependence of the observed shapes on the $p_T$ of the associated particles can be used to distinguish conical emission from a sonic boom (Mach-cone) and from QCD-Cerenkov radiation. We present results from STAR on 3-particle azimuthal correlations for a high $p_T$ trigger particle with two softer particles. Results are shown for $pp$, d+Au and high statistics Au+Au collisions at $\sqrt{s_{NN}}$=200 GeV. An important aspect of the analysis is the subtraction of combinatorial backgrounds. Systematic uncertainties due to this subtraction and the flow harmonics v2 and v4 are investigated in detail. The implications of the results for the presence or absence of conical flow from Mach-cones are discussed.

description: Jean-François Eck analyses the development of regional consciousness in the French coalfield Nord-Pas-de-Calais during the 20th century. ough extraction of coal began relatively early with the first coal mine that has been sunk in 1716 a regional consciousness was formed not until the 19th century. Having remained steady up to the 1950s regional consciousness was seriously disturbed by the closure of collieries and underwent substantial changes thereafter. From 1955 to 1990 collective identity perished until a new mentality was shaped on the basis of a revaluation of the industrial heritage which reveals both chances and potentials of the structural change.

VP17-02 : Enhanced coercivity in SmCo4Cu thin films induced by chromium interlayer

Thin Films, Multilayers and Interface Effects (Virtual)
Sm(Co,Fe,Cu,Zr)z alloys exhibit a characteristic microstructure comprising of SmCo5 phase, Sm2Co17 and Zr-rich platelets that intersect these phases. The unique microstructure of these alloys makes them superior high-temperature permanent magnets. However, owing to the intricate nature of the material, numerous questions remain unanswered, concerning the impact of individual phases on magnetic performance[1-2]. Research indicates that the thickness of the Z platelets play a critical role in determining the magnetic properties of the alloy. Specifically, increasing the thickness of the Z phase leads to a significant reduction in coercivity[3]. By exploring the impact of an antiferromagnetic interlayer between the Sm-Co layers in thin film model systems grown by molecular beam epitaxy (MBE), we have achieved to increase coercivity. Antiferromagnetic layers have been investigated in exchange bias systems, but have never been explored in connection with ultrahard magnetic materials and permanent magnetic properties. Expanding upon our understanding of Sm-Co thin films[4-5], we initiated our investigation by introducing Cr layers of varying thicknesses into a simplified system where Cr interlayers were sandwiched between layers of SmCo4Cu. The films have been grown on Al2O3 substrates and have been characterized by X-ray diffraction (XRD) and superconducting quantum interference device (SQUID). Our findings provide clear evidence that the Cr layer within a specific thickness range can enhance coercivity. Cross-sectional high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM) images provided visual evidence of sharp and coherent interface between the layers. Detailed chemical composition mapping of all elements, obtained through STEM/EDX, revealed a uniform distribution of chromium without any discernible diffusion into the Sm-Co layer. Our study offers new research opportunities in investigating the impact of functional layers, which are not conventionally part of the standard Sm-Co-Fe-Cu-Zr alloy composition. By widening the range of available phases in the development of future magnetic systems we can push the boundaries and unlock new possibilities for innovative magnetic materials.References: [1] M.
