title: Field induced multiple magnetization plateaus in NdPt2B studied by single crystal neutron diffraction.

description: NdPt2B crystallizes in a non-centrosymmetric hexagonal structure. Resistivity, specific heat and susceptibility data reveal three antiferromagnetic transitions at TN1 = 19.5 K, TN2 = 11 K, and a first-order transition at Tm = 9.5 K. Our neutron diffraction study on powder and single crystal samples (with B-11) using D20 and WISH instruments revealed an original ground state. It can be represented as a superposition of three unharmonic spin density waves, combining k=(0,0,1/5), 2k=(0,0,2/5) and k=0 components at 2K, with moments polarized within the (ab)-plane and forming 60- and 120-degrees configuration. The stacking of the moments along the c-axis follows +-++-+ sequence, where + and – stand for positive and negative moment direction along the in-plane easy axes of the spin density waves. Interesting the magnetization isotherm for H//a-axis at 2 K and below 2 T exhibits multiple magnetization plateau (five metamagnetic transitions) and saturates above it. The prosed magnetic ground state can naturally explain this behaviour by assuming that magnetic field flips some negative spins to positive, changing the periodicity (propagation vector) of the structure. We, therefore, proposed to carry out a single crystal neutron diffraction study in applied field (H//-axis) on NdPt2B to investigate the changes in the magnetic structure across the magnetization plateau.

title: Proton tunnelling in intramolecular hydrogen bonds: a neutron study

description: Zero-point vibrational energy (ZPE) and nuclear quantum tunnelling (NQT) are nuclear quantum effects (NQEs) that can be measured directly only using neutron Compton scattering (NCS). This proposal’s ambition is to extend the applicability of the NCS technique on VESUVIO into the realm of the local proton quantum dynamics in the intramolecular hydrogen bonds by investigating two benchmark systems for studying hydrogen tunnelling, malonaldehyde (MA) and tropolone (TR), in both hydrogenated and OD-deuterated forms. The ground-state tunnelling splitting in both MA and TR was investigated both experimentally and theoretically, and the main result was that the tunnelling would be partially quenched when the transferring hydrogen is substituted by deuterium. However, in the most recent theoretical study of proton tunnelling in the MA, Roberto Car et al. authors proposed that the correlations of the molecular motions are sufficient to smooth non-Gaussian NMDs associated with deep tunnelling in the one-dimensional double-well model. However, in the TR, this smoothing mechanism may not exist. The proposal aims at checking this hypothesis.

title: Quantum tuning of magnetic phases in vanadium sulphide single crystals

description: Strongly correlated electron systems are known to host a variety of exotic phenomena and novel quantum phases. The transition-metal chalcogenide system, VxS8, is of particular interest, for it displays a wide range of behaviour on changing the stoichiometry, from a charge density wave metal (x=4) to an antiferromagnetic metal (x=5, 6) and even, a paramagnet metal (x=8). Here, we focus on V5S8, where we have observed that magnetic interactions between the vanadium d-electrons lead to an antiferromagnetic phase below 32K. We now propose to use the Wish instrument to explore the rich magnetic phase space available in this compound, by conducting a series of both powder and single-crystal neutron diffraction experiments at both zero and non-zero magnetic fields.

title: Hydrogenation of superconducting cuprate thin films studied by neutron reflectometry

description: Hydrogenation of thin films allows for targeted and in many cases reversible modification of their structural, electronic, and magnetic properties. In the case of the cuprates, hydrogen doping offers an additional degree of freedom to access the rich phase diagram [4], and specifically to tune the superconducting transition temperature Tc. The aim of the experiment is to understand the incorporation mechanism and the hydrogen-induced effects. Essential for understanding the hydrogen-incuced effects is the depth resolved measurement the H concentration in the layers and at the interfaces. Neutron reflectometry is the only method providing these data in direct and non-destructive way, in contrast to x-ray reflectometry, which is not sensitive to hydrogen and and sees only indirect effects of hydrogenation, such as lattice expansion and layer swelling.

title: Mixed surfactants under extreme conditions

description: Previous experiments have shown effects of mixing ionic and non-ionic surfactants over a range of Ts at ambient conditions (RB2210186). The aim of this experiment is to study these systems under extreme Ts/Ps, to model in-engine conditions, using a specialised T/P cell loaned from ILL (pre-agreed between ISIS and ILL instrument scientists). This would explore novel concepts in colloids science. Using this specialised sample environment it will be uniquely possible to achieve “iso-density” solvents (see Figure 1) which would enable us to access new solvent landscapes.

title: The behaviour of iron carbonyl, Fe(CO)5, at high pressure

description: Iron pentacarbonyl is an iconic molecule with widespread applications in organometallic chemistry. However, its behaviour at non-ambient conditions is poorly known. In 2020 we carried out a low-temperature study using HRPD, from which we identified a new polymorph that becomes stable below 105 K. At high pressure, there is only a single study carried out in a diamond anvil cell using Raman spectroscopy [Ryu et al., Sci. Rep., 5, 15139: 2015], which found two high-P polymorphs, phases II and III, followed by decomposition at ~ 15 GPa. We aim to test the hypothesis that our low-T structure corresponds with the first high-pressure polymorph (phase II, stable above 1 GPa at room temperature), to determine the structure of the unknown phase III (stable above 5 GPa at room-T), and to measure the equations of state of phases I, II and III.

description: Clay minerals are the most abundant material in the world and can be used in basic research as well as in many industrial applications. The aim of this proposal is to investigate delaminated synthetic fluorohectorite high-aspect-ratio clay under different external conditions. We are working on the controlled swelling of synthetic clay minerals into clay nanosheets for the capture of large molecules and nanoparticles in the clay interlayers, and also for structural coloration, where the interlayer spacing can reach the order of hundreds of nanometers.

title: Solvation structure of hexane/hexene in [C4mim][NTf2] ionic liquid

description: There are great energy costs associated with the separation of olefins from mixed hydrocarbon gas and liquid feeds. These olefins (obtained from natural gas, biosources, or produced from recycling of waste hydrocarbons) are chemical starting materials for high-demand materials such as PET, PPE, PVC, solvents, lubricants and medications. Ionic liquids have been suggested as low energy intensive absorbent materials that could selectively capture and release these olefins from mixtures without the need to use the expensive and energy intensive separation methods. This study aims to provide important contributions towards the understanding and comparison of hydrocarbon absorption and separations in ionic liquids at a molecular level and in the hydrocarbon gas and liquid phases. In turn this will allow the designing of sorbents with improved performance leading to the evaluation of their use in an industrial setting.

title: Magnetic Properties of Quaternary Selenides

description: We will investigate magnetic ordering in Cu2MGeSe4 (M = Mn, Fe, Co), for which magnetic susceptibility data indicate a transition to antiferromagnetic order at temperatures in the range 10–20 K. The Mn- and Co-containing phases exhibit Curie-Weiss behaviour at high temperatures with effective magnetic moments in good agreement with spin-only values. The Fe analogue exhibits more complex behaviour with a second feature observed in the susceptibility below TN and a broad maximum in the high-temperature susceptibility, leading to non-Curie-Weiss behaviour. We seek to determine the magnetic structure for each phase, and its evolution with temperature, by collection of data at base temperature and on warming through TN. We will extend the collections to higher temperature for the Fe analogue to understand the origin of the different behaviour exhibited by this phase.
