title: Proximity-Induced Magnetism in CrTe2/Bi2Te3 Ferromagnet-Topological Insulator Heterostructures

description: Topological electronics explores novel quantum properties encountered in topological insulators (TIs). TIs exhibit remarkable features, including dissipationless carrier transport through their surface states. When TIs are magnetically doped, they can display the quantum anomalous Hall effect (QAHE)—a zero-field version of the ordinary quantum Hall effect. However, due to defects associated with doping, the useful temperature range for QAHE is limited. By bringing a magnetic material close to a TI, the TI’s surface states can acquire magnetic properties via proximity-induced magnetism (PIM). We recently discovered that Mn diffusion in the leading Mn-based heterostructures can mimic the elusive PIM effect at the interface.

To address this problem, have recently studied the NiO/Bi2Te3 system with PNR, and found that despite its superb structural quality, the magnetic complexity of the NiO layer makes drawing unambiguous conclusions about PIM difficult. Here, we propose to study CrTe2/Bi2Te3 heterostructures by PNR, which have two outstanding properties. First, the 1T- CrTe2 layer has a well-defined (out-of-plane) magnetic anisotropy. Second, since the nuclear SLD of the two layers is very similar, small changes in the magnetic SLD at the interface will have a huge effect on the spin asymmetry, hopefully allowing, for the first time, to get unambiguous proof of the existence of the elusive PIM effect.

title: An investigation of chromotropic behaviour in anils using combined neutron diffraction and Raman spectroscopy

description: Following the conclusion of a facility development project to develop a new sample environment allowing simultaneous in-situ neutron diffraction and Raman spectroscopy, we propose to study photoisomerization in 3,5-di-tert-butylsalicylidene-3,4dimethoxyanline, and proton migration in-salicylidene-2,5difluroanline and 3,5-di-tert-butylsalicylidene-2,4difluroanline. These compounds are chromotropic and such behaviour is associated with the transfer of a hydrogen atom from the oxygen atom of a phenolic group to a nitrogen atom to produce an enamine. The proton migration occurs either by thermal (thermochromic) or light stimuli (photochromic) and the possibility of studying the structural features and the Raman response at the same time will probe the mechanisms of action in fine details whilst building fundamental knowledge to be used for further calculations on these systems

title: Possible spin-liquid state in the rare-earth based kagome antiferromagnet

description: The interplay between spin-orbit coupling, spin correlation, and crystal electric field in rare-earth-based geometrically frustrated magnets offers a promising ground for the search for enigmatic quantum spin liquids (QSL). QSL is a highly entangled state ideal to host fractional excitations coupled to emergent gauge fields and has immense potential for braiding quantum computing technology. However, the experimental realization of QSL is a challenging theme due to the presence of defect and disorder in real quantum materials. Here, we focus on a new rare-earth-based spin-lattice Pr3BWO9 wherein Pr3+ ions constitute a two-dimensional corner shared triangles decorating a kagome quantum magnet. Neither magnetic susceptibility nor specific-heat data show any signature of long-range magnetic ordering or spin freezing down to 70 mK despite a sizable Curie-Weiss temperature of θcw = - 6.8 K. This calls for more sensitive local-probe magnetic investigations that could unambiguously confirm the spin-liquid ground state and characterize the corresponding magnetic excitations at very low temperature given the rather weak exchange coupling between Pr3+ moments. We propose a µSR study at sub-kelvin temperatures to provide valuable insight and confirm the spin-liquid conjecture in this novel rare-earth-based kagome lattice antiferromagnet family and to explore the role of rare-earth ions on the quantum-disordered state.

title: Investigation of the Groundstates of 5d1 and 5d2 Osmate and Rhenate Double Perovskites by Neutron Powder Diffraction

description: Double perovskites hosting transition metals with 5d1 and 5d2 electronic configurations are widely considered as candidate materials hosting exotic physical groundstates from a theoretical standpoint. However, the characterization of these groundstates by neutron scattering has proven difficult. In this proposal, we aim to perform careful neutron powder diffraction measurements on a collection of 5d1 and 5d2 double perovskites, both rhenate and osmate variants (Ba2MgReO6, Ba2LaReO6, Ba2LiOsO6, and Ba2CaOsO6), possessing a range of observed physical properties in these systems. We plan to use the WISH diffractometer, which we consider to have the best possibility currently available in the global community to observe magnetic scattering from these small moments and determine the subtleties of the magnetic and crystal structures of these materials. The results are expected to have considerable impact on the understanding of spin-orbit coupled physics in heavy transition metal materials.

title: Eu3Bi2S4F4: uncovering mysteriously suppressed superconductivity using F–µ–F states

description: Cuprate superconductors have attracted considerable research interest over the past few decades due to their high transition temperatures which 
allows superconductivity to be accessed at liquid nitrogen temperatures. In light of this, there has been considerable effort in finding materials with similarities to cuprates which may also exhibit superconductivity at high temperatures. One of the promising families of materials are those formed of BiS2-layers, which tend to have a crystal structure analogous to cuprates. One of the most recently discovered compounds which exhibits superconductivity is Eu3Bi2S4F4, which consists of Eu3F4 layers which crystalize into a CaF2-like structure (where the fluoride ions are in a simple cubic arrangement), sandwiching bilayers of BiS2. Polycrystalline samples of this material shows a superconducting transition below about 1.5K, but this is not present in single crystal samples. This experiment aims to find out why, by observing the way in which the F--mu--F state changes with temperature for both single crystal and polycrystalline samples.

title: Mapping of residual stress distribution in spin formed Aluminium alloy component

description: Spin forming technology is a potentially attractive manufacturing platform for high-volume production of liquid hydrogen storage tanks in future hydrogen powered aircraft to deliver the net zero solution in air transportation. However, the non-uniform local deformation state occurred during metal spinning process generates non-uniform residual stress distribution and this has a significant impact on the service performance and post-processing of the components. The proposed studies are focused on the use of Engin-X neutron diffractrometer to generate maps of residual stress distribution over the entire spin formed AA5085 aluminium alloy parts in the form of either dome or cup shape, so to establish a fundamental understanding of interplay between process, part geometry and residual stress in spin formed components.

title: Vibrations affect social organisation in termites

description: Datasets - Data_ergatoids / Data_soldiers

These data were collected on 16 colonies of the species termite Reticulitermes flavipes (column: colony_id). New reproductive and soldiers were counted every day. Newly differentiated reproductive were recognized thanks to the elongated abdomen and colour changes. Newly differentiated solider were recognized using the presence of highly developed mandibles. The day of differentiation of an individual ranged from 0 to 60 (column: day). Six different treatments were used: (i) two playbacks with a conserved original structure of the peaks recorded in the presence of reproductive (column treatment: Original +) and in the absence of reproductive (column treatment: Original -); (ii) two playbacks with a structure randomly transformed from the original recordings (called random) were recorded in the presence of reproductive (column treatment: Random +) and in the absence of reproductive (column treatment: Random -); (iii) two controls composed of 100 workers in the presence (column treatment: Control +) or absence (column treatment:  Control -) of 2 reproductive (1 female and 1 male; brachypterous neotenic).

The differentiation of an individual is annotated as 1 (column: diff_ergat), associated with the day of differentiation (column: day). Note that many individuals did not differentiate into reproductive or soldiers during the experiment (column: day = 60, column: diff_ergat = 0 in the dataset).

title: Hydrogen dynamics in TiFe alloys with Zr and Hf additions

description: The metal hydride TiFe is presently used commercially for hydrogen storage. However, the first hydrogenation is difficult and the hydrogen capacity drop with cycling. One way to solve these problems is to add Zr or Hf as additive in the melt. We want to see how the hydrogen vibration states change when Zr or Hf is added and also if there is some relationship with decrease capacity. The two compositions TiFe + 4 wt.%Zr and TiFe + 4 wt.%Hf will be investigated in three different hydrogen loading to see the effect of hydrogen capacity on the vibration states. We estimate that only one measurement at 10K will be sufficient for each composition and hydrogen loading. Two days will be sufficient to perform all the intended measurements.
