The charge transfer compound CuTCNQ (TCNQ = 7,7,8,8-Tetracyanoquinodimethane) exhibits switching between two electrical resistance states when subject to an electric field. It...

The structure of the phosphate materials Na_{1+x}Ge_{2-x}Al_x(PO_4)_3 with x = 0, 0.4 and 0.8 will be investigated using high real-space resolution neutron diffraction. In the...

The presence of a Hebel-Slichter peak in NMR or µSR measurements just below the critical temperature of superconductors is taken to be strong evidence for conventional behaviour...

Alkali-cluster intercalated fullerides (LixC60, NaxC60) proved to be suitable materials for solid state hydrogen storage. In these compounds the hydrogen is chemically absorbed...

We have recently observed extraordinary polymorphism on cooling various sodalites under vacuum. Materials undergo a phase transition followed by a fully reversible...

Magnetic properties of graphitic compounds are of current interest for both theoretical and experimental research in the fields of condensed matter physics and magnetism. In the...

The mechanism of high temperature superconductivity (HTSC) remains unresolved. Of particular interest is the origin of the mysterious pseudogap (PG, a partial gap in the...

CeAuAl3 and CeCuAl3 compounds crystallize in the tetragonal I4mm, BaNiSn3-type and display interesting bulk properties. Here we propose to investigate the magnetic structures of...

We aim at performing temperature (2-300K) and magnetic field (0-5T) dependent muon SR on a 1X1 cm2 mosaic, made of 4* 5x5x2 mm3 TbMn0.98Fe0.02O3 single crystals (largest area...

Orientationally-disordered water molecules in ice adopt a degree of partial order upon cooling, a process that is halted by kinetics at ~100 K in pure ice and ~60 K in KOH-doped...

We have synthesized a new cobalte oxide compound. We know from preliminary measurements that its crystal structure is hexagonal, and that the magnetic behaviour is intriguing....

In this proposal we aim to understand the solvation of AB by two of the most important solvents ? ammonia and THF. Neutron diffraction is a key technique in this context because...

In a typical magnetic material the interactions between neighbouring magnetic moments will tend to lead to their ordered alignment throughout the entire structure as it is...

We request 3 days of beamtime on GEM to attempt to perform neutron diffraction on helium inside vitreous SiO2. Significant amounts of helium can be dissolved into the glass...

Osmium-based oxides show a wide range of interesting properties due to the variety of oxidation states osmium can adopt combined with 5d electrons displaying strong spin-orbit...

The topotactic reduction of Sr3Co2O5Cl2 and Sr3Co2O5.80 yields the Co(II) phases Sr3Co2O4Cl2 and Sr3Co2O5 respectively. These phases contain corner linked arrays of...

Principal Component Analysis (PCA) is a powerful chemometric tool for the analysis of multivariate datasets. Capitalising from the recent upgrade of the TOSCA spectrometer, we...

We aim to perform inelastic neutron scattering (INS) measurements at the TOSCA spectrometer to study the vibrational behaviour of designer Guest@MOF composite systems (e.g....

We propose to study the influence of deposition rates and annealing effects on microporous amorphous solid water samples (ASW) using NIMROD. The data will allow us to monitor...

Thermoelectric (TE) materials are set to play an increasingly important role in the development of new energy efficient technologies by generating electrical current from waste...
