VP11-03: Enhancement of magnetoelectric coupling in laminate composites of textured Fe-Ga thin sheet and PZT
Creators: Jiande Liu
Publisher: name: IEEE
Year: 2023

Multi-Functional Magnetic Materials and Applications (Virtual)
Multiferroic magnetoelectric (ME) coupling between the magnetostrictive and piezoelectric constituents has superior ME properties and shows promising potential for practical applications such as sensors, transducers, energy harvesters, etc [1-3]. More attention was focused on improving the ME coupling by utilizing different piezoelectric constituents with superior properties [3-4]. The ME coupling can also be enhanced by improving the magnetostrictive materials. Compared to the brittle of Terfenol-D, Galfenol (Fe-Ga) exhibits a combination of high mechanical strength and good ductility, allowing it to be used in harsh and shock-prone environments [5,6]. However, the larger ME output was limited by its low magnetostrictive coefficient. In this study, the laminate composites of the ME sandwich structure device were fabricated using a PZT piezoelectric ceramic plate polarized along the thickness direction sandwiched between two Fe-Ga thin sheets prepared by conventional rolling and annealing methods. Goss-oriented and random-textured Fe-Ga thin sheets were prepared to reveal the effect of texture and magnetostriction coefficient on the ME coupling. The ME laminate with Goss-oriented Fe-Ga sheet and magnetostrictive coefficient of 244 ppm exhibits much higher ME coefficients (73.11 V/cm●Oe) than those of ME laminate (16.17 V/cm●Oe) with random-textured Fe-Ga sheet and magnetostrictive coefficient of 64 ppm. Meanwhile, higher ME coefficients can be obtained in a low resonance frequency (26.4 Hz) and excitation magnetic field (26 Gs).References: [1]H. Liu, J. Wang and H.

Local application and precise tunability of large magnetic fields would bear an enticing prospect for generating and detecting Majorana fermions. Such functionality can be readily achieved using Superconductor (S) /Ferromagnet (F) bilayers, where superconductivity is strengthened on top of domain walls due to local lowering of the proximity-induced large effective exchange fields resulting in significant Tc enhancements and possible magnetic switching of this domain wall superconducting (DWS) phase. Using Nb and ferromagnetic insulating (GdN) bilayers and detailed magneto-transport measurements, we demonstrate previously unobserved phenomena of strengthening the DWS phase with shrinkage of cooper pairs. In the thinnest of Nb layers, we estimate in congruence with the theory of domain wall superconductivity that this tunability of proximity-induced exchange fields must be as high as 1.3T with an application of in-plane external fields of few mT.

Due to its excellent magnetic properties, endless effort has been paid to the exploration of high performance Nd-Fe-B permanent magnets since its discovery [1]. Experimental maximum energy product [(BH)max] has reached 59.5 MGOe, which is approximately 93% of the theoretical value. Heavy rare earth (HRE) elements addition is inevitable in order to meet the requirements of high temperature working stability in motors. There is still a significant gap between the coercivity reported and the calculated value in HRE free magnets, which seriously limits the further applications of the sintered Nd-Fe-B permanent magnets [2, 3]. Grain boundary diffusion (GBD) process can enhance coercivity of the magnets effectively with limited HRE usage [4]. However, it should be noted that applicable thickness limitation on the GBD magnets is prominent because of relatively low diffusion depth and diffusion efficiency. In this work, we report a study on the microstructure and magnetic properties of the Zr-doped Nd-Fe-B magnet with GBD treatment. R(Nd,Pr,)-T(Fe,Co,Cu,Al,Ga,Zr)-B sintered magnets with different Zr addition (0.1 wt%, 0.2 wt%, 0.4 wt%) were prepared by typical powder metallurgy method. Tb70Cu15Ga15 powders with an average particle size of ~8 μm were used as the HRE diffusion source here. Increment of coercivity varies greatly between 6 kOe and 11 kOe in magnets with different Zr addition. A greater abundance of ZrB2 precipitates were found to be presented at the GBs in the magnet with high Zr addition, which strongly influence the microstructure of GB phases and diffusion process of HRE elements in the magnets. HRE-rich shell and diffusion depth can be significantly improved with appropriate Zr addition after GBD treatment. Present study provides new insights into the manufacture of the magnets with high coercivity and low HRE content.References: [1] M. Sagawa et al., J. Appl. Phys., 55, 2083-2087 (1984). [2] X. D.

3D Magnetism
The distinct characteristics and potential uses of magnetic vortex in ferromagnetic films have garnered significant interest in the field of magnetism [1]. The challenge of maintaining vortex stability in small sizes, which was constrained by patterned films on 2D plane [2], was overcome by implementing films on 3D structures [3]. This breakthrough was achieved through Landau-Lifshitz-Gilbert (LLG) simulation, which indicates a specific feature such as breaking points (BPs) in magnetization-magnetic field (M-H) curves implying the existence of stable vortex in 3D pyramidal shapes [4]. However, there is no experimental research indicating BPs in M-H curves due to the challenges encountered in the method used for sample growth. In our group, experimentally, we successfully produced 3D pyramidal Fe nanofilms using a combination of photolithography of Si substrates and Si surface treatments [5-6] for Fe deposition, resulting in BPs implying vortex formation [7]. Fig.1 shows the schematic of an Fe film on a 3D Si{111} pyramidal structure; 16 µm edge length and 50 nm of Fe thickness were prepared. Fig. 2 shows M normalized by the saturation magnetization (Ms) as a function of H applied in pyramid outer edge direction (|| Si[110]) measured by vibration sample magnetometer (VSM) at room temperature, displaying certain BPs corresponding vortex. To confirm the presence of magnetic vortex, we combined longitudinal magneto-optic Kerr effect (MOKE) microscopy, judging initial magnetization direction denoted by white arrows in Fig. 1. Clearly right (left) oriented magnetization close to the apex on the upper (downer) 3D-Fe pyramidal facet plane, indicating stable vortex is seen; note little information for right and left facets because M should be perpendicular to H. We noticed magnetization direction on 3D-Fe edge area close to 2D Fe oriented to left direction due to magnetic interaction between 3D and 2D Fe area, which would prevent the vortex formation. In the presentation, we will also demonstrate the results for patterned 3D-Fe pyramids without 2D Fe area.References: [1] N. S. Kiselev, A. N. Bogdanov, R. Schafer, et al., J. Phys. D: Appl.

description: Optical-field emission from nanostructured solids such as subwavelength nanoantennas can be leveraged to create sub-femtosecond, PHz-scale electronics for optical-field detection. One application that is of particular interest is the detection of an incident optical pulse's carrier-envelope phase. Such carrier-envelope-phase detection requires few-cycle, broadband optical excitation where the resonant properties of the nanoantenna can strongly alter the response of the near field in time. Little quantitative investigation has been performed to understand how the geometry and resonant properties of the antennae should be tuned to enhance the carrier-envelope phase sensitivity and signal to noise ratio. Here we examine how the geometry and resonance frequency of planar plasmonic nanoantennas can be engineered for enhancing the emitted carrier-envelope-phase-sensitive photocurrent when driven by a few-cycle optical pulse. We find that with the simple addition of curved sidewalls leading to the apex, and proper tuning of the resonance wavelength, the net CEP-sensitive current per nanoantenna can be improved by $5$-$10\times$, and the signal-to-noise-ratio by $50$-$100\times$ relative to simple triangular antennas operated on resonance. Our findings will inform the next generation of nanoantenna designs for emerging applications in ultrafast photoelectron metrology and petahertz electronics.

Current transformer is one of the most widely used equipment in power systems, including energy metering and relay protection[1, 2]. But when the core of the CT occurs saturation, the secondary current will be distorted, which may affect the accuracy of electric energy measurement or cause the malfunction of the relay protection equipment, thereby having certain impacts on the stability of the power grid[3, 4]. In order to address the problem, a novel measurement-protection-integrated current transformer based on composite core (MPICT) is proposed in this paper. The configuration of MPICT, mainly including composite core, secondary winding, magnetic sensor, operational amplifier, and power amplifier, is shown in Fig 1. The composite core used in MPICT includes a complete annular core and an annular core with several air gaps, which is called lower core and upper core respectively. A magnetic sensor is placed in the air gap of the upper core to measure the magnetic field strength. After sequentially processed by the operational amplifier and the power amplifier, the output of the magnetic sensor is added to the secondary current. In order to verify the effectiveness of the MPICT, the actual prototype are built. The rated primary current of the prototype is 1000A, and the rated secondary current is 5A. The rated output is 15VA. The material of the lower core is amorphous alloy, while the upper core is made of silicon steel. The magnetic sensor used in the prototype is the tunnel magnetoresistance sensor with the model of TMR2651. Table 1 shows the errors of MPICT when the rms of primary currents are 10A, 50A, 200A, 1000A, 1200A, and 10000A, respectively. According to IEC 61869-2, MPICT can simultaneously meet the accuracy class 0.2S and 5P10. When the primary current is a short-circuit current with a transient factor of 2 and a primary time constant of 60ms, the composite error of MPICT is 2.98% that is still less than 5%. In summary, the novel current transformer designed in this paper can not only meet the accuracy class for measuring current transformers, but also satisfy the error limits for protective current transformers without significantly increasing the volume.References: [1] R.

Soft magnetic particles with micron-size are widely used in high frequency devices, i.e. inductor, noise suppressor because of high saturation magnetization and flexibility in shape. For the next-generation devices in several GHz range, eddy current becomes serious problem due to low resistivity. One of the effective ways to solve this problem is to reduce the particles size to less than the skin depth. Previously, we reported submicron-sized Fe-B amorphous particles synthesized by aqueous solution reduction method[1]. It found that ferromagnetic resonances were observed in the range of 1 to 3 GHz and their intrinsic permeability were 9-14. Herein, we newly synthesize submicron-sized Fe-B particles doped with Ni and evaluate their structures and magnetic properties. Figure 1 shows SEM image of as-made Fe-Ni-B particles. The particles were non-agglomerative and spherical shape with the median size of approximately 200 nm and the size distribution of 150-250 nm. Similar shape and median size were observed in the annealed particles at 400 for 1 h in Ar ambient. In both samples with and without annealing, the amorphous phase was confirmed by TEM observation. Figure 2 shows the complex permeability (μ' and μ") of the Fe-Ni-B particles composites. μ’ increased from 2 to 2.8 after annealing process. In case of μ’’, broad peaks were observed in both samples. And value of μ’’ was almost zero up to 1 GHz for the annealed sample. This indicates the high frequency magnetic properties were improved by annealing process, which might be attributed to the structure relaxation. In conclusion, these results suggest that submicron-sized Fe-Ni-B particles possess good high-frequency magnetic properties by annealing process.References: [1] K. Murata, T. Miyazaki, H.

Magneto-ionic and New Magnetoelectric Materials
INTRODUCTION Magnetocapacitance (MC) is the property of any dielectric or heterostructure that shows change in the value of capacitance when magnetic field is applied externally. It can be an intrinsic property of the solid or extrinsic as well due to interface effects [1]. The intrinsic MC effect is found in multiferroic compounds and composites with the magnetoelectric coupling [2] and extrinsic effect relates to the contribution of magnetoresistance (MR) effect, spin accumulation at the interface [3],[4]. In the present work, we study effect of inhomogeneity on spin accumulation reflected using MC in the conjugated polymers. The conjugated polymers are expected to have rich electron path networks formed out of coiling or reticulation. These are electrically inhomogeneous and form scattering sites. For this study we choosed PANI, which is one of the important electronic materials. ABSTRACT The magnetoimpedance effect allows us to estimate the extent of spin dependent scattering in disordered solids. The change in impedance with respect to applied magnetic field manifests through local change in permeability on the surface and it amplifies at defect sites. The local electrical inhomogeneities are expected to aid this effect through spin dependent scattering. The conjugated electrical networks provide a significant scope for producing spin dependent scattering mediated by path defects and protonic charge accumulations. This hypothesis is investigated in the present work taking polyaniline as a prototype network. The electrical inhomogeneities in the network were controlled by selective oxidation and aging in polyaniline. The Giant Magnetoimpedance (GMI) was observed in these networks with the change of the order of 50-60% for lower frequencies with prominent capacitive coupling and colossal change of the order of 200% at higher frequencies with prominent inductive coupling. However, the no spin accumulation was observed in the insulating network units. This study is expected to a serve as a tool to develop frequency selective spin accumulation based magnetic field sensors and oscillator networks.References: [1].

description: This paper proposes a novel sandwich design for improved out-of-plane stiffness in the Double Parallelogram Flexure Mechanism (DPFM). In DPFMs and flexure mechanisms comprising DPFMs, low in-plane stiffness along the motion direction helps improve the range of motion and reduces the actuation effort. On the other hand, high out-of-plane stiffness is essential to support large payloads and minimize out-of-plane parasitic motions. Achieving both of these design objectives simultaneously is challenging in DPFMs due to the inherent tradeoff between the in-plane and out-of-plane mechanics. The novel sandwich DPFM design proposed in this paper achieves a significant improvement in the out-of-plane bearing stiffness without affecting the in-plane motion-direction stiffness, thereby overcoming the tradeoff between the out-of-plane and in-plane stiffness values. Analytical models are presented for the out-of-plane and in-plane stiffness of the sandwich DPFM, which match very closely with Finite Element Analysis (FEA) predictions. The superior performance of the sandwich DPFM is demonstrated and several design insights are presented using the analytical stiffness models.

description: In the spring of 2020, the Department of Informatics covered a 20 ECTS capstone course in Software Engineering, mainly focusing on developing a complex application. The course used active learning methods, and 240 students were working in 42 cross-functional, agile teams. The pandemic caused by the coronavirus had a significant impact on the teaching given by the University of Oslo, as all physical education and collaboration among the teams had to be digital from March 12. At the end of the semester, we conducted a survey that focused on 1) aspects of teamwork (e.g., communication and coordination in the teams) and the relation to team performance (e.g., the application product) and 2), the students' motivation and ability to cooperate through digital platforms. A total of 151 respondents in 41 agile student teams answered the survey. This study aimed to investigate how the teamwork and motivation of the students were affected by having to work virtually. The results are compared to results from the same course in 2019 and a similar survey on 71 professional teams published in 2016. Our results show that the teamwork was evaluated similarly to both the evaluation of survey conducted in 2019 and on the professional teams in 2016. The motivation among the students remained high, even though they had to collaborate virtually.

Local parametric poisson models for fisheries data
Creators: name: Yee, Irene Mei Ling
Publisher: name: University of British Columbia
Year: 2010

description: Poisson process is a common model for count data. However, a global Poisson model is inadequate for sparse data such as the marked salmon recovery data that have huge extraneous variations and noise. An empirical Bayes model, which enables information to be aggregated to overcome the lack of information from data in individual cells, is thus developed to handle these data. The method fits a local parametric Poisson model to describe the variation at each sampling period and incorporates this approach with a conventional local smoothing technique to remove noise. Finally, the overdispersion relative to the Poisson model is modelled by mixing these locally smoothed, Poisson models in an appropriate way. This method is then applied to the marked salmon data to obtain the overall patterns and the corresponding credibility intervals for the underlying trend in the data.

description: JavaScript has become one of the most widely used programming languages for web development, server-side programming, and even micro-controllers for IoT. However, its extremely functional and dynamic features degrade the performance and precision of static analysis. Moreover, the variety of built-in functions and host environments requires excessive manual modeling of their behaviors. To alleviate these problems, researchers have proposed various ways to leverage dynamic analysis during JavaScript static analysis. However, they do not fully utilize the high performance of dynamic analysis and often sacrifice the soundness of static analysis. In this paper, we present dynamic shortcuts, a new technique to flexibly switch between abstract and concrete execution during JavaScript static analysis in a sound way. It can significantly improve the analysis performance and precision by using highly-optimized commercial JavaScript engines and lessen the modeling efforts for opaque code. We actualize the technique via $\text{SAFE}_\textsf{DS}$, an extended combination of $\text{SAFE}$ and Jalangi, a static analyzer and a dynamic analyzer, respectively. We evaluated $\text{SAFE}_\textsf{DS}$ using 269 official tests of Lodash 4 library. Our experiment shows that $\text{SAFE}_\textsf{DS}$ is 7.81x faster than the baseline static analyzer, and it improves the precision to reduce failed assertions by 12.31% on average for 22 opaque functions.

The valve reactor (VR) with multiple magnetic cores is an important electrical equipment in the UHVDC system. The large amplitude and fast changing pulse current during its operation can cause high temperature rise in the VR, threaten the thermal aging of the insulation, and even cause serious accidents such as combustion and explosion. Therefore, it is necessary to accurately quantify the loss characteristics of VR under different ferromagnetic materials. This article consists of the following three sections: 1. Theoretical Analysis The VR consists of several magnetic cores evenly distributed in the cooling-water winding, along with casing. The magnetic core is made of ultra-thin silicon steel sheets, and the casing is filled with Epoxy resin and Polyurethane, as shown in Figure 1. The current during operation is shown in the figure, and the heat source includes winding loss and magnetic core loss. 2.Finite Element Simulation Analysis of Electromagnetic Fields Simulations are conducted separately for single magnetic cores using GT100 and 30Q130 materials. The finite element simulation results of the magnetic field distribution and electromagnetic loss of a single magnetic core, as well as the temperature distribution of each magnetic core of the VR, are shown in Figure 2. 3.Conclusion This article establishes a VR 3D model of actual size and performs VR finite element simulation on different materials，obtaining the following conclusions: 1) The distribution of magnetic flux density of the magnetic core is higher on the inner side compared to the outer side. 2) The average loss of a single magnetic core using GT100 is 109.6W, compared to 121.4W for 30Q130 Thinner silicon steel laminations result in lower losses. 3) The overall temperature distribution of VR is step-like temperature distribution with high in the middle and low on both sides， and the temperature of the magnetic core near the water inlet is lower than that far away from the water inlet.References: [1] Wang Q, Liu P and Tian H, High Voltage., 7. 2, p.288-301 (2022) [2] Cao J, Davidson C and Moulson S, IET Science Measurement & Technology., 1. 3, p.138-144 (2007) [3] Yang W, Chen W and Zhou Y, High Voltage., 5.3, p.598-604 (2019) [4] Li X, Zha J and Wang S, IEEE Transactions on Dielectrics & Electrical Insulation., 24.6, p.3898-3905 (2018) [5] Cao J, Ji F and Liu J, IET Science Measurement & Technology., 10.2, p.77-83 (2016)

description: We propose a new concept of two-dimensional (2D) Dirac semiconductor which is characterized by the emergence of fourfold degenerate band crossings near the band edge and provide a generic approach to realize this novel semiconductor in the community of material science. Based on the first-principle calculations and symmetry analysis, we discover recently synthesised triple-layer (TL)-BiOS2 is such Dirac semiconductor that features Dirac cone at X/Y point, protected by nonsymmorphic symmetry. Due to sandwich-like structure, each Dirac fermion in TL-BiOS2 can be regarded as a combination of two Weyl fermions with opposite chiralities, degenerate in momentum-energy space but separated in real space. Such Dirac semiconductor carries layer-dependent helical spin textures that never been reported before. Moreover, novel topological phase transitions are flexibly achieved in TL-BiOS2: (i) an vertical electric field can drive it into Weyl semiconductor with switchable spin polarization direction, (ii) an extensive strain is able to generate ferroelectric polarization and actuate it into Weyl nodal ring around X point and into another type of four-fold degenerate point at Y point. Our work extends the Dirac fermion into semiconductor systems and provides a promising avenue to integrate spintronics and optoelectronics in topological materials.

description: We calculate the intensity of the polariton mediated inelastic light scattering in semiconductor microcavities. We treat the exciton-photon coupling nonperturbatively and incorporate lifetime effects in both excitons and photons, and a coupling of the photons to the electron-hole continuum. Taking the matrix elements as fitting parameters, the results are in excellent agreement with measured Raman intensities due to optical phonons resonant with the upper polariton branches in II-VI microcavities with embedded CdTe quantum wells.

description: Key to successfully deal with complex contemporary datasets is the development of tractable models that account for the irregular structure of the information at hand. This paper provides a comprehensive and unifying view of several sampling, reconstruction, and recovery problems for signals defined on irregular domains that can be accurately represented by a graph. The workhorse assumption is that the (partially) observed signals can be modeled as the output of a graph filter to a structured (parsimonious) input graph signal. When either the input or the filter coefficients are known, this is tantamount to assuming that the signals of interest live on a subspace defined by the supporting graph. When neither is known, the model becomes bilinear. Upon imposing different priors and additional structure on either the input or the filter coefficients, a broad range of relevant problem formulations arise. The goal is then to leverage those priors, the shift operator of the supporting graph, and the samples of the signal of interest to recover: the signal at the non-sampled nodes (graph-signal interpolation), the input (deconvolution), the filter coefficients (system identification), or any combination thereof (blind deconvolution).

description: Given a finite irreducible Coxeter group $W$, a positive integer $d$, and types $T_1,T_2,...,T_d$ (in the sense of the classification of finite Coxeter groups), we compute the number of decompositions $c=\si_1\si_2 cdots\si_d$ of a Coxeter element $c$ of $W$, such that $\si_i$ is a Coxeter element in a subgroup of type $T_i$ in $W$, $i=1,2,...,d$, and such that the factorisation is "minimal" in the sense that the sum of the ranks of the $T_i$'s, $i=1,2,...,d$, equals the rank of $W$. For the exceptional types, these decomposition numbers have been computed by the first author. The type $A_n$ decomposition numbers have been computed by Goulden and Jackson, albeit using a somewhat different language. We explain how to extract the type $B_n$ decomposition numbers from results of Bóna, Bousquet, Labelle and Leroux on map enumeration. Our formula for the type $D_n$ decomposition numbers is new. These results are then used to determine, for a fixed positive integer $l$ and fixed integers $r_1\le r_2\le ...\le r_l$, the number of multi-chains $π_1\le π_2\le ...\le π_l$ in Armstrong's generalised non-crossing partitions poset, where the poset rank of $π_i$ equals $r_i$, and where the "block structure" of $π_1$ is prescribed. We demonstrate that this result implies all known enumerative results on ordinary and generalised non-crossing partitions via appropriate summations. Surprisingly, this result on multi-chain enumeration is new even for the original non-crossing partitions of Kreweras. Moreover, the result allows one to solve the problem of rank-selected chain enumeration in the type $D_n$ generalised non-crossing partitions poset, which, in turn, leads to a proof of Armstrong's $F=M$ Conjecture in type $D_n$.

description: We introduce new techniques based on brane tilings to investigate D3-branes probing orientifolds of toric Calabi-Yau singularities. With these new tools, one can write down many orientifold models and derive the resulting low-energy gauge theories living on the D-branes. Using the set of ideas in this paper one recovers essentially all orientifolded theories known so far. Furthermore, new orientifolds of non-orbifold toric singularities are obtained. The possible applications of the tools presented in this paper are diverse. One particular application is the construction of models which feature dynamical supersymmetry breaking as well as the computation of D-instanton induced superpotential terms.

description: The electromagnetic polarizabilities of the nucleon are shown to be essentially composed of the nonresonant $α_p(E_{0+})=+3.2$, $α_n(E_{0+})=+4.1$,the $t$-channel $α^t_{p,n}=-β^t_{p,n}=+7.6$ and the resonant $β_{p,n}(P_{33}(1232))=+8.3$ contributions (in units of $10^{-4}$fm$^3$. The remaining deviations from the experimental data $Δα_p=1.2\pm 0.6$, $Δβ_p=1.2\mp 0.6$, Δα_n=0.8\pm 1.7$ and $Δβ_n=2.0\mp 1.8$ are contributed by a larger number of resonant and nonresonant processes with cancellations between the contributions. This result confirms that dominant contributions to the electric and magnetic polarizabilities may be represented in terms of two-photon couplings to the $σ$-meson having the predicted mass $m_σ=666$ MeV and two-photon width $Γ_{γγ}=2.6$ keV.

description: Associated to the classical Weyl groups, we introduce the notion of degenerate spin affine Hecke algebras and affine Hecke-Clifford algebras. For these algebras, we establish the PBW properties, formulate the intertwiners, and describe the centers. We further develop connections of these algebras with the usual degenerate (i.e. graded) affine Hecke algebras of Lusztig by introducing a notion of degenerate covering affine Hecke algebras.
