title: Diffusion and Lattice Dynamics in Disordered Li Argyrodites

description: Lithium argyrodites Li6PS5X (X=Cl, Br) have been demonstrated as promising solid-state electrolytes (SSEs) for next-generation batteries owing to their high ionic conductivity. Yet, the key atomistic processes enabling their fast ionic diffusion remain poorly known. It is believed the X/S site disorder plays an important role in Li diffusion. However, this explanation ignores the correlated dynamics between Li diffusion and host lattice, which we have recently uncovered its importance. Specifically, based on inelastic neutron scattering and quasi-elastic neutron scattering measurements on Li6PS5Cl, supplemented with AIMD and machine-learning accelerated MD simulations, we have gained important insights into the coupling of fast ion diffusion with anharmonic framework phonons.

Here, we propose to study the lattice dynamics and ion diffusion on Li6PS5Br with different degrees of S/Br disorder by QENS (and INS). By this systematic study, we will separate effects of structural disorder vs framework vibrations on ionic conductivity, and also get a better understanding of the correlation between phonon dynamics and diffusion behavior in SSEs upon structural changes. This project will refine our understanding of the correlation between phonon dynamics and Li diffusion, building on top of our previous findings, and potentially provide an important insight into how to further increase ion diffusion in SSEs via phonon-engineering.

title: Characterization of soil-water-root interactions in saline and sodic soils using correlative imaging techniques

description: Increased soil salinity and sodicity (amount of sodium held in a soil) pose significant environmental threats to soil health in arid and semi-arid regions, leading to reduced crop productivity and biodiversity. These processes can be attributed to both natural factors, such as climate and topography, and human activities, particularly irrigation practices. Inappropriate irrigation management, excess use of irrigation water and low water quality are major causes of soil salinity and sodicity in many areas of the world. Irrigating soils with poor quality irrigation water is the primary cause of the development of saline soils, affecting cultivation of crops and crop yields due to osmotic stress. The hypothesis is that in the addition that the soil pore system characteristics are affected by irrigation-induced salinity and sodicity, roots systems are also affected, and such effects can be captured by combining the neutron imaging technique available on IMAT (ISIS) with the high-resolution x-ray imaging setup at I12-JEEP (Diamond Light Source).

title: Powder-neutron-diffraction study of magnetic structure on frustrated Ba3MnTa2O9

description: Two- dimensional (2D) triangular lattice antiferromagnets (TLAF) offer exotic magnetic phases and have attracted a lot of attention in recent times. A new Mn2+ (S=5/2) based TLAF Ba3MnTa2O9 has been synthesized in polycrystalline form using a solid-state reaction method and characterized using HRXRD, dc, and ac susceptibility and heat capacity measurements. Rietveld refinement of XRD data suggests that the material crystallizes in a trigonal crystal structure with space group P-3m1. The crystal structure comprises edge-shared triangular layers of Mn2+ ions in the crystallographic ab-plane which are well separated (7.1252 Å) along the crystallographic c-direction making it effectively a 2D TLAF. The Curie-Weiss fit of susceptibility above 100 K yields θCW ~ -10 K, indicating a dominant antiferromagnetic interaction between Mn2+ ions. The effective magnetic moment (µeff ~ 5.8 µB) is close to the theoretical value of ~5.9 µB for isolated Mn2+ ions. A hump at ~3K in ac susceptibility (χ’) and heat capacity data suggest the onset of a magnetic ordering. The neutron powder diffraction technique will be useful for studying the spin structure of Ba3MnTa2O9 in the ordered state.

title: CANADIAN: Momentum dependence of crystal field levels in CeRhIn5

description: In Kondo systems, localized f-electron states hybridize with itinerant electrons, leading to an emergent many-body state. Modern electronic structure calculations indicate that excited crystal electric field (CEF) and spin-orbit levels of the f-electron manifold need to be considered in strongly correlated metals such as the Kondo materials. Recent RIXS and ARPES experiments both indicate that these excited states acquire momentum dependence due to Kondo hybridization. Through the dynamical magnetic susceptibility, neutron scattering should access another aspect of this interesting momentum dependence. Yet, we are not aware of any single crystal neutron scattering studies of heavy fermion materials that could shed light Q-dependences of CEF levels. To investigate this subject, we propose to measure the single crystal inelastic spectrum of the heavy fermion material CeRhIn5 with the MAPS spectrometer with an incident energy of 50 meV. We request a total of 8 days to measure Q-dependences of the CEF levels in the antiferromagnetic, coherent paramagnetic and incoherent paramagnetic phases. The experiment will be performed on a well-characterized sample that has already been used to study the low-energy spin wave excitations.

title: Crystal electric field measurement of the Kosterlitz-Thouless phase candidate TmZn2GaO5 without structural disorder

description: An emergent U(1) symmetry and the Kosterlitz-Thouless phase have been proposed in the transverse field Ising model on the antiferromagnetically coupled triangular lattice. This was initially thought to be realized in TmMgGaO4, which however turned out elusive as the Mg/Ga disorder induces extra complexity.
We have newly synthesized TmZn2GaO5 where Tm3+ ions reside on the perfect triangular lattice but with no Mg/Ga disorder. It is promising to yield unambiguous result for the long persuit KT phase in 2D magnets. As the first step, we propose to perform inelastic neutron scattering experiment to measure the CEF levels to construct the effective spin model.

title: MuSR studies of complex magnetism in topological kagome magnets GdMn6Sn6 and DyMn6Sn6

description: Inspired by the recent observation of highly unusual spin fluctuations that coexist with the long-range magnetic order in TbMn6Sn6 via muSR, we would like to propose a similar ZF-muSR study of large single crystals of the topological kagome metals GdMn6Sn6 and DyMn6Sn6 (up to ~2 g each) at the RIKEN-RAL muon instrument ARGUS or CHRONUS, in the temperature range of 1.5-450 K. We would like to request 3 days of beamtime. We believe that the new insights into the complex magnetic ordering and the possible interplay between the localised rare-earth magnetism, itinerant Mn magnetism and non-trivial band topology in this fascinating topological quantum material series can be obtained with the proposed experiments.

title: Kinetics of Soil-Release Polymer Activity at Model Fabric Interfaces

description: Soil release polymers work in laundry products by adsorbing onto fabric surfaces and either preventing adhesion of soils to surfaces or redeposition of soils from solution during laundering. We have started to explore this process at the nm scale using neutron reflection in order to validate predictive models in a large collaborative project. Our focus in this proposal is to explore the detailed kinetics of adsorption of both soil release polymers and models for complex soils, for a well defined model system.

title: Characterisation of octahedral hexahalo compounds.

description: We have recently investigated a series of compounds by inelastic neutron scattering, (INS) and conventional optical spectroscopies, to generate complete and unambiguous assignments for all the modes. One of the aims of the work was to see if there are any systematic trends that can be exploited to estimate the (usually) optically inactive mode ?6, if the other modes are known. A plot of ?5 vs ?6 shows that there is generally a good correlation between the two mode energies. We propose to measure the INS spectra of WF6 and MoF6, which will provide an unambiguous assignment of ?6 because of the absence of selection rules. We also propose to measure SF6 and WCl6, the former because it will provide confirmation of existing assignments and the latter because it will allow a comparison with WF6. In all four molecules, ?6 has only been observed indirectly from overtone and combination bands.

title: Temperature control of enhanced magnetic damping in ferrimagnetic Ni/Tb bilayers

description: Future magnonic devices which manipulate spin wave excitations as opposed to charge currents, offer a pathway towards novel, high performance and low-energy magnetic-logic devices. Here, magnetic damping is a crucially important parameter, controlling energy dissipation within the system. There is also emerging interest in the use of rare earth-transition metal (RE-TM) alloys and multilayer systems due to the ferrimagnetic nature of these systems, resulting in a plethora of useful phenomena, including ultrafast, energy efficient switching. While the mechanism for damping when interfacing magnetic thin films with conventional large spin orbit coupling materials such as Pt is well understood, it is far from clear within a RE-TM multilayer system, where large damping enhancements may arise from coupling between the elements. 
In this proposal, we aim to examine the coupling of NiFe/Tb bilayers through Polarised Neutron Reflectivity (PNR) as a function of temperature. Temperature is a well established parameter for tuning the behaviour of RE elements within RE/TM systems, and the use of a depth sensitive probe such as PNR will allow us to determine the strength and thickness limits of any magnetic coupling within the system and the role it plays in enhancing the damping. Additionally, looking at this as a function of temperature will allow us to better understand the role of the magnetisation within the Tb layer, allowing us to further the capabilities of future devices.

title: Elucidation of the structural transformation of MIL-53(Al) upon D2 responsive 2nd Breathing

description: MIL-53(Al), a well-known flexible MOF, exhibits a dynamic 'breathing' phenomenon, transitioning from narrow pore (np) to large pore (lp) states. Understanding the structural flexibility of MIL-53(Al) holds the key for advancements, making it ideal for precise gas separation, including hydrogen isotopes. This proposal seeks beamtime to investigate unresolved questions concerning MIL-53(Al)'s isotope-specific second 'breathing' transitions induced by D2 adsorption below 25 K. To date, neutron powder diffraction (NPD) studies have been hampered by high noise levels. Leveraging the superior flux of the WISH beamline, we aim for precise identification of D2 adsorption sites and their site-specific binding energies as functions of pressure. Concurrently, we will examine how crystal size influences the kinetics of these transitions. We can readily prepare pure-phase MIL-53(Al) with high crystallinity over 1 g of the material for gas loading experiments. To complete these experiments, it will require approximately three days for in situ NPD measurements. We believe that NPD, benefiting from the high flux of WISH, is the optimal tool for this purpose, allowing us to identify hydrogen isotope adsorption sites within MIL-53(Al).
