We propose to measure the inelastic scattering S(Q,E) maps from gallium in its liquid phases across a wide range of temperatures. This proposal is based on a new prediction for...

Finely divided supported palladium particles are used as catalysts in many technical processes. Using MAPS we have recently investigated the interaction of hydrogen with the...

Co3Sn2S2 is a metallic ferromagnet with Tc = 177 K, which crystallizes in a shandite-type structure. Below the Curie temperature its electronic structure forms a half-metal...

We recently discovered new members of the stoichiometric 1-3-7 family of crystals including YbRh3Si7, YbIr3Ge7, CeIr3Ge7, and YbIr3Si7, whose magnetic and transport properties...

This proposal is part of our research programme to explore the experimental manifestation of topological properties of magnetic excitations. The honeycomb ferromagnet is...

For non-Fermi liquid compounds, the dynamical susceptibility, as determined from inelastic neutron scattering, is particularly interesting as it exhibits universal energy...

Preliminary data on the spin excitation spectrum of the honeycomb lattice compound Na2Co2TeO6 are consistent with the existence of Kitaev interactions, as was recently proposed...

Superconductors have many practical applications, especially in technologies that require high magnetic fields, such as magnetic resonance imaging (MRI). Efforts to find new and...

Rare-earth frustrated systems can present exotic physical properties. The newly discovered TmMgGaO4 shares the same structure as the quantum spin liquid candidate YbMgGaO4 with...

To understand the thermal conductivity suppression within PGEC titanate oxide thermoelectrics we hope to complement theoretical calculations performed on several perovskites...

The method of Se isotope substitution with inelastic neutron scattering will be used to measure the partial VDOS for As2Se3 glass. This is a prototypical network forming...

There is considerable interest in understanding the magnetoelectric effect with the aim of developing technological applications. Until recently this has been limited to...

The single band Hubbard model is considerably the simplest effective model that includes both the delocalizing/hopping energy and the on-site interaction for describing strongly...

With this experiment we aim to investigate the role of spin orbit coupling (SOC) in 4d transition metal oxides.In previous inelastic neutron scattering experiments on the parent...

We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One...

The present proposal is part of a larger EPSRC project advancing the vibrational spectroscopy of silicate glasses. The project involves the techniques of IR and Raman...

SrCuO2 is a prototypical S = 1/2 antiferromagnetic (AF) Heisenberg 1D spin chain system. High-resolution neutron scattering studies has already successfully revealed the gapless...

The colossal magnetoresistance effect in manganites arises from a competition between delocalisation, which favours a ferromagnetic metallic phase, and localisation of electons...

We propose to study the magnetic excitation spectrum of Na2IrO3 with inelastic neutron scattering. Na2IrO3 is a promising candidate to realize Kitaev interaction. By mapping out...

We have discovered an unusual magnetovolume effect in the 6H-perovskite oxides Ba3BiIr2O9 and Ba3BiRu2O9. These compounds contain isolated face-sharing bi-octahedral dimers...
