title: Suppression of quantum fluctuations by high magnetic field in one- and two-dimensional spin-1/2 magnets.

description: Fluctuations in the properties of materials at low temperatures give rise to unusual and exotic effects. These fluctuations, quantum mechanical in origin and allowed by the Heisenberg uncertainty principle, affect both magnetic and metallic systems, and could be responsible for formation of high temperature superconductivity in certain materials. These effects are expected to be suppressed by applying high magnetic fields, but only limited experimental evidence for the suppression has so far been observed real materials. We propose measurements on two recently discovered magnetic materials which, owing to their molecular building blocks, allow access to a more extensive range of field-induced physics than was previously possible. We will make use of the 14 T superconducting magnet available at WISH, the instrument most ideally suited to this measurement.

title: The mechanical stability of austenite in 3rd generation advanced high strength steels

description: Advanced High Strength Steels are of great interest for the automotive industry. The key to getting an optimal mechanical response of these steels is to control the deformation-induced austenite to martensite transformation. However, the austenite resistance to transformation has not been well understood yet due to the complexities involved in studying the transformation process and decoupling the different microstructural factors influencing the stress/strain-induced transformation. In order to identify the role of the starting microstructure on the mechanical stability of austenite, we propose to conduct in-situ tensile tests at room temperature on microstructures specifically designed to study austenite grain size, austenite morphology and the surrounding mechanical constraint effects on the mechanical stability of austenite.

title: Studies on Novel Frustrated Quantum Magnets: Ba2YbMO6 (M = Nb, Ta) via muon spin rotation

description: Frustrated systems, where spins are prevented from ordering collinearly because of the geometry of interactions, have attracted interest because of the emergent phenomena related to noncollinear spin arrangements and degenerate ground states. It has been proposed that the degenerate nature of the ground states in some frustrated systems can be broken by quantum fluctuations and host nontrivial topological states. In particular, the quantum Kitaev face-centered-cubic (FCC) system is suggested to have gapless pseudo-Goldstone modes and a Weyl node in its magnon band. By measuring the spin waves of quantum Kitaev FCC candidate system, Ba2YbMO6 (M = Nb, Ta), we want to demonstrate this nature.

title: Probing interactions in polymer and biosurfactant mixtures: a step towards a bio-sustainable shampoo?

description: Biosurfactants are surface active molecules that are produced by a variety of microorganisms and plants. They have a growing profile as they are bio-sustainable and biodegradable. In order to evaluate their possible use in formulations (shampoos, detergents, etc), understanding their interactions with commonly used polymers in these formulations is important, as mixtures of synthetic polymers/surfactants with biosurfactants is showing to be the most promising route to incorporate them in formulations. In this proposal we wish to probe these interactions with/without an anti-dandruff agent (Piroctone olamine) using SANS.

title: Study of the magnetization reversal mechanism in antiferromagnetic interlayer exchange coupling in LaCaMnO/CaRuTiO superlattices

description: In the year of 2017, our group reported the antiferromagnetic interlayer exchange coupling (AF-IEC) in La2/3Ca1/3MnO3/CaRu1/2Ti1/2O3 superlattices, which is the first time the AF-IEC phenomenon observed in an all-oxide-based system. The results have attracted wide attention for the delicate step-like reversal of magnetic moments in different layers. However, the exact micro-scale reversal mechanism cannot be revealed by traditional measurements. To solve the question, we need to obtain the magnetic depth profile in different states, that is, the ferromagnetic, the antiferromagnetic and the intermediate state. Polarized neutron reflectometry is a powerful tool to clarify the microscopic magnetic structure and help to figure out the crucial physical issues.

title: ECG measurement from the hand with single fingers - elbows resting on the armrests of the chair - Man 29 age

description: The data set shows the measurements of the ECG signal from the hand made with the use of the proprietary measuring system, based on the AD8232 and STM32 chips. Thanks to such a constructed device, it is possible to measure the ECG signal in a non-standard way - from the hand. The results show the ECG signal for a specific hand and forearm position relative to the body and to the measuring device. With the help of the presented results, it is possible to determine or test the best possible hand layout in order to record data in which individual anatomical features are eliminated as well as possible.

title: ISIS@MACH - Neutron Spectroscopy of leather artefacts from Museo Egizio (TOSCA)

description: Within the Museo Egizio collection there are 200 precious and unique leather artefacts belonging to different historical periods including the Old Kingdom, New Kingdom, Roman and Byzantine eras. Leather materials were used in everyday applications, subject to hard use and harsh environmental conditions. Here we propose to study the structure, dynamics and elemental composition of leather artefacts spanning from the Old Kingdom to the Byzantine Period and including samples from the intact tomb of Kha (around 1400 BC) that document an extensive crystallization phenomenon. The experimental investigation will be performed using Inelastic Neutron Scattering (INS) on TOSCA and Time of Flight – Prompt Gamma Activation Analysis (T-PGAA) on VESUVIO beamlines at ISIS pulsed neutron and muon source, through the Neutron Gate of ISIS@MACH.

title: Spin dynamics in the new spin ice candidate Nd2Pt2O7

description: Most of Nd-pyrochlores show all-in-all-out long-ranged order ground state at low temperatures. Nd2Zr2O7 reveals magnetic fragmentation in the spin ice state, and its antiferromagnetic order is proposed to be induced by the monopole crystallization [1]. Recently unconventional slow spin dynamics are reported in the paramagnetic state of pyrochlore insulators Nd2Sn2O7 [2] and Nd2Zr2O7 [3], which is suspected coming from the spin ice state in the compounds. We have successfully synthesized Nd2Pt2O7 polycrystalline sample which exhibits an antiferromagnetic order at 1.4 K in the heat capacity measurements. Ferromagnetic signature is observed in the magnetization measurements, suggesting probably spin fragmentation in the compound. The high ordering temperature and ferromagnetic components in Nd2Pt2O7 suggests a strong mechanism of the monopole crystallization.

title: Probing Spin Dynamics in an S=1/2 Spin Liquid Candidate: Metal-Organic Framework

description: Quantum Spin Liquids (QSL) are magnetic materials with no long range ordering. We would like to explore the magnetic ground state of a Copper based Metal-Organic Framework (MOF) with suspected quantum spin liquid behaviour. Our magnetization data gives a strong indication of the absence of long range magnetic ordering at low temperature even though strong antiferromagnetic interaction is present in the system, which can be ascertained from Curie-Weiss law.The triangular arrangement of Cu2+ ions along with the magnetic results makes the system extremely interesting from the QSL standpoint. We have also done some preliminary measurements in MuSR beamline which suggests the spins in the system to be dynamic in nature. In this study, we propose to probe the spin dynamics of this MOF at milli Kelvin temperature using dilution refrigerator.

title: Thermal expansion and magnetostriction in fayalite, Fe2SiO4

description: Olivines - in particular the solid-solution between forsterite (Mg2SiO4) and fayalite (Fe2SiO4) - are important rock-forming minerals on Earth, also occurring in meteorites and interstellar dust. Olivines form the major component of Earth's upper mantle and the point at which their structure becomes unstable with respect to denser minerals marks the upper boundary of the transition zone between the upper and lower mantle. The thermal expansion of fayalite (Fe2SiO4) is unusual and not well understood at present. The expansion coefficients of two of the axes of the crystal have a "normal" temperature dependence, tending to zero as T goes to 0 K and becoming almost constant at high T; however, for the other axis the expansion coefficient is roughly constant between about 80 K and 1100 K. The purpose of our experiment is to understand the structural basis of these differences in behaviour

title: Nature of Quantum Spin-liquid Ground State of a Honeycomb Kondo Lattice CePt6Al3 : µSR study

description: Recently, Honeycomb lattice materials have attracted considerable attraction due to the bond dependent exchange proposed by Kitaev. We have synthesised a new Ce-based Honeycomb compound CePt6Al3, which exhibits heavy Fermion behaviour and no clear sign of long range magnetic ordering. However, heat capacity exhibits a broad maximum at 0.55K indicating the development of short range correlations. Our inelastic neutron scattering (INS) study reveals one CEF excitation near 15meV at 5K, but dramatic change in the excitations at 110 and 170K, suggesting new kind of excitations. It is an open question whether the ground state is magnetic or quantum spin-liquid. We therefore propose to investigate the magnetic ground of CePt6Al3 using muon spin rotation and relaxation on MuSR/EMU. The proposed uSR results with our existing INS data will allow us to publish our results in a high impact journal.

title: muSR study of the Fe-substitution effects on ferromagnetic fluctuations in heavily overdoped Bi-2201 cuprates

description: Recently, it has been suggested in heavily hole-doped high-Tc cuprates that ferromagnetic (FM) fluctuations exist and compete with the superconductivity. Moreover, we have found that 5% Fe substitution for Cu in heavily overdoped Bi-2201 cuprates brings about the coexistence of enhanced FM fluctuations and a spin-glass state of Fe spins. The purpose of this proposed study is to clarify the Fe-induced magnetic states in Fe-substituted Bi-2201 cuprates, changing the Fe content systematically, from muSR measurements down to 0.3 K. This study combined with our electrical-resistivity and magnetic-susceptibility measurements would provide significant information on the nature of the FM and spin-glass states in the heavily overdoped cuprates, leading to the understanding of the superconductivity and FM fluctuations.

title: Characterization of a spin-liquid state in the triangular lattice antiferromagnet PrTa7O19

description: Rare-earth based geometrically frustrated magnets represent a promising new avenue for the search of enigmatic quantum spin liquids (QSL). These are disordered states with strong quantum entanglement and exotic magnetic excitations. In our study, we will focus on a novel triangular lattice antiferromagnet PrTa7O19, a sister compound of the previously studied NdTa7O19, where such effects might take place. Our preliminary bulk magnetic characterizations don’t show any signature of magnetic ordering in this material. This calls for more sensitive local-probe magnetic investigations that could unambiguously confirm the spin-liquid ground state and characterize the corresponding magnetic excitations. A µSR study at sub-kelvin temperatures should provide a valuable insight and confirm the spin-liquid conjecture in this novel rare-earth based triangular lattice antiferromagnet.
