title: SANS study of the random VC precipitation kinetics in Nanosteels

description: Nano-steels are a new generation of Advanced High Strength Steels (AHSS), extremely suitable for lightweight automotive applications. The matrix of the steel, which provides ductility and stretch, is significantly strengthened by manometer-sized precipitates, which can increase the strength level by 30-50%. These steels contain different micro-alloying additions, such as vanadium (V) and molybdenum (Mo), which form the essential nano-precipitates. A resource-efficient use of these alloying additions requires further knowledge on the formation kinetics of these nanometer-sized vanadium carbides (VC). The formation of these nano-scale VC precipitates can be achieved by two mechanisms: (a) random precipitation from supersaturated ferrite and/or (b) interphase precipitation. Our previous studies have focused on interphase precipitation. In this experiment we want to explore random precipitation. Our aim is to measure the random VC-precipitation kinetics in NANO-steel by SANS and elucidate the effects of V addition.

title: Mapping the spin correlations in the single crystal of a novel triangular lattice antiferromagnet ErTa7O19

description: Rare-earth (RE) based geometrically frustrated magnets represent a promising avenue in the search of enigmatic quantum spin liquids (QSLs). Our previous study has identified a novel family of RE heptatantalates RETa7O19, where in the Nd case strong Ising anisotropy on the triangular lattice leads to a QSL state. As the nature of the RE ions can strongly influence the magnetic anisotropy we initiated a study of isostructural ErTa7O19 with twice stronger magnetic interactions. Recent neutron diffraction measurements done on the WISH instrument revealed sizable magnetic diffuse scattering as a signature of short-range spin correlations. Here we propose a single crystal neutron diffraction study on the WISH instrument to map and compare the in-plane and out-of-plane spin correlations in the reciprocal space.

title: Novel ground state in the honeycomb-lattice antiferromagnet Co2Te3O8

description: Frustrated magnets wherein competing magnetic interactions between spins induce strong quantum fluctuations have attracted intensive attention in view of realizing exotic magnetic phases with anisotropic interactions, quasi-particle fractionalization, and long-range entanglement. Of particular interest, enormous efforts have been devoted towards the experimental realization of emergent quasi-particle excitations such as spinons with the signature of quantum entanglement even in the magnetically ordered state. Alexei Kitaev proposed an exactly solvable highly anisotropic Kitaev model for S = 1/2 spins on the honeycomb spin-lattice. Contrary to an isotropic nearest-neighbor exchange model on the honeycomb-lattice, which exhibits long-range order, the ground state of the Kitaev model is a quantum spin liquid (QSL) with fractionalized Majorana fermions and gauge flux excitations. Here, we focus on a new Co2+ structurally perfect honeycomb lattice antiferromagnet that shows an antiferromagnetic ordering at 53 K. The magnetic entropy suggests the presence of short-range spin correlations. We, therefore, propose neutron diffraction measurements at sub-Kelvin temperatures to probe the nature of the ordered magnetic ground state, i.e. commensurate or incommensurate. The proposed study will enable us to extract the relevant order parameter, correlation length, and critical exponents essential to establish a universality class in this novel frustrated antiferromagnet.

title: Quantifying the Extent of Improved Li-ion Motion using Quasi-Elastic Neutron Scattering

description: Sulphide superionic materials are candidate electrolytes for all-solid-state batteries. Quasi-elastic neutron scattering (QENS) is sought to obtain bulk diffusion rates and activation energies for three Li6PS5Cl electrolytes prepared by different methods; a standard cold pressed electrolyte, a heat-treated electrolyte and a spark plasma sintered version. The ionic conductivity of the heat treated and plasma sintered Li6PS5Cl samples are substantially greater than that of the commercial cold pressed material. The post-processing noted above, typically promotes grain growth which leads to enhanced conductivities, however structural modifications when using these post processing methods has also been observed. QENS will allow us to determine the true bulk diffusion, which can then be compared to macroscopic diffusion (which considers bulk, grain boundary, and particle interface diffusion) determined by pulsed field gradient nuclear magnetic resonance allowing us to elucidate which of these factors is rate limiting for effective ion diffusion.

title: A muSR study of magnetic properties of the Meissner phase.

description: A recent LE-muSR experiment brought unexpected results challenging the standard interpretation of electromagnetic properties of the Meissner phase, i.e., properties of the bulk of superconducting samples in the Meissner state. However, these results could be an artifact caused by a low-energy tail of the stopping distribution of implanted muons. Here we propose an experiment that excludes the possibility of such an artifact, tests the previous finding, and explores it over a broader range of fields and temperatures of the Meissner phase.

title: Temperature-dependent phonon transport in nanocellulose materials

description: Nanocellulose-based foams can display super-insulating properties which is proposed to be controlled by interfacial phonons scattering. We propose to use inelastic neutron scattering to probe the phonon density of states (DOS) as a function of temperature and follow the phase transitions related to the hydrogen bonds. Combing the phonon DOS with simulations will help us decipher the dynamics within our samples and clarify the underlying mechanisms behind the phonon transport and the effect temperature has, aiding the future development of super insulating materials.

title: Crowding and salinity effects on the structure of PEG-containing brushes

description: Strongly hydrated polymers are used as coatings for biofouling prevention, and poly(ethylene glycol) (PEG) is a widely used example of this. Wider use of PEG is limited by insufficient stability but this can be improved by adding PEG sidechains to a more stable polymer backbone. However, this alters the structural properties in ways that can be difficult to predict. Here, we will explore the properties of polymer brushes with PEG sidechains from two aspects:
i) These brushes show thickness-dependent antifouling performance, which has been associated to differences in hydration and crowding of the polymer with thickness, but further details about the structure, in particular qualitative and quantitative differences in the chain segment density distributions, would considerably improve our understanding and facilitate the development of these brushes into practical coatings.
ii) Poor antifouling performance of PEG in solutions of high salinity is hypothesized to be an effect of the recently proposed charging of PEG in aqueous solutions due to adsorption of hydronium ions. If correct, this would imply some degree of polyelectrolyte properties, and subsequent structural changes at high salinity, which we will explore as well.

title: Strain-mediated parallel to antiparallel magnetic switching of twisted LSMO bilayers on PMN-PT

description: Strain-mediated magnetoelectric (ME) coupling in ferroelectric (FE) and ferromagnetic (FM) heterostructures provides an exciting path towards the development of next-generation memory storage and sensing technologies. This proposal aims to use Polarized Neutron Reflectometry (PNR) to investigate ME coupling in twisted bilayers of La(1-x)Sr(x)MnO3 (LSMO) membranes stacked on a substrate of the giant piezoelectric (1-x)Pb(Mg1/3Nb2/3)O3-(x)PbTiO3 (PMN-xPT). The piezo-driven coupling between the LSMO bilayers and PMN-PT will switch the LSMO magnetic moments from a parallel state to an anti-parallel state, which will be measured using PNR. This strain-mediated switching does not rely on the use of external factors (such as shape anisotropy) or a multi-step voltage application process and should garner broad interest in the multiferroic research community.

title: Magnetic structure of a Pd-doped Honeycomb Kondo Lattice Ce(Pt1-xPdx)6Al3

description: Recently the Honeycomb lattice has attracted considerable attraction due to the bond dependent exchange interactions according to the Kitaev model, resulting in a quantum spin-liquid ground state previously identified in -RuCl3. We have synthesised a new Ce-based Honeycomb lattice compound CePt6Al3, which exhibits heavy-fermion behaviour and no clear sign of long-range magnetic ordering down to 0.05 K. At low temperatures the resistivity exhibits T2 behaviour without showing any anomaly down to 0.05 K. The heat capacity (C/T) exhibits a broad maximum of 0.5 J/K2 mol at around 0.55 K. The ground state appears to be a heavy-fermion state where the Kondo effect and frustration cooperatively prevent the Ce magnetic moments in the honeycomb lattice from long-range ordering. Interestingly, the heat capacity of Ce(Pt1-xPdx)6Al3 with x = 0.1-0.3 exhibits a λ-type peak between 2 and 3 K indicating a long-range magnetic ordering, which is confirmed by our muon spin rotation measurements. We therefore propose to investigate the magnetic structure of Ce(Pt1-xPdx)6Al3 with x=0.1 and 0.3 using the high flux WISH diffractometer.

title: Destabilization Pathways in Organometal Halide Perovskites

description: Organometal halide perovskites are the current focus of attention as a new class of materials for photovoltaic and photonic applications, with efficiencies already above 20%. Critical issues remain, primarily associated with their physico-chemical stability and their propensity to degrade over time. Building upon our works on these materials using TOSCA and parallel methodological developments on the instrument, this proposal seeks to obtain new and much-needed insights into their destabilization pathways and the role of hydrogen-bonding in driving these. To this end, we would need TOSCA and its new high-pressure capabilities to conduct experiments in the GPa domain on selectively deuterated specimens of methylammmonium lead iodide. These results will give us direct access to the local structure and vibrations immediately before structural collapse and amorphization.

title: Neutron Diffraction study to determine the magnetic structure of Ce2RuGe

description: Ce2RuGe which crystallizes in orthorhombic structure (space group Pmmn) has been found to exhibit an antiferromagnetic ordering below TN = 12 K and undergoes another transition to a ferromagnetically ordered state below Tc = 8.5 K. In this structure Ce atoms occupy two crystallographic positions Ce1 and Ce2, and it has been suggested that the Ce atoms occupying Ce1 sites exhibit valence fluctuating behaviour whereas the Ce atoms occupying Ce2 site exhibit long-range magnetic ordering. The occurrence of two transitions near 12 K and 8.5 K are consistently seen in magnetic susceptibility, heat capacity and electrical resistivity data. The 12 K transition seems to have an antiferromagnetic character whereas the 8.5 K transition depicts a ferromagnetic character. Further investigations using the neutron diffraction experiment are highly desired to determine the magnetic structure of this compound. We propose to carry out neutron diffraction measurements on Ce2RuGe using WISH diffractometer to determine the magnetic structure and understand the nature of magnetic moments on two Ce sites in this compound.
