In materials with correlated disorder (i.e. not completely random nor completely ordered), new physics and functionalities can occur. Correlated disorder can be treated...

New electronic phases often emerge in the proximity of a quantum critical point (QCP) - that is the point where the transition temperature of a collective phase transition is...

A large amount of contemporary research by both chemists and physicists is focused on exploiting the spin of electrons with the attempt of revolutionising the current technology...

SMMs have received much attention owing to their quantum tunneling and slow relaxation of the magnetization. This has led to an intense activity by synthetic chemists to...

Most of our technology is based on the use of charge, however the electron also has another less well-understood (or exploited) property called spin. The application of this...

We recently observed a resonant spin excitation in Ba1-xKxFe2As2 (x=0.4), one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates...

Recently it has been reported that YbAl3C3 undergoes an antiferromagnetic quadrupolar ordering transition at 80 K, Further study by Ochiai et al. revealed that the transition at...

We want to investigate the collective dynamics of water at intermediate length scales (below the first structure factor peak and approaching the hydrodynamic range). To...

Type-I clathrates are of active interest for thermoelectric applications at temperatures above room temperature. This is mostly due to rattling modes of the guest atoms in these...

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...

Our recent inelastic neutron scattering (INS) study using MARI clearly reveals the presence of a sharp inelastic excitation near 8 meV and 11 meV in CeT2Al10 (T=Ru and Os)...

It is well known that water is the medium in which the overwhelming majority of biological processes take place. In cell membranes water molecules are thought to be essential to...

Recently a great deal of theoretical and experimental interest has been directed at a class of magnetic materials which undergo phase transitions at zero temperature. These...

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...

Several non-centrosymmetric heavy-fermion compounds have been reported to exhibit unconventional superconductivity (SC). For example, both CeRhSi3 and CeIrSi3 order...

We propose to investigate the magnetic excitation spectra of tetravalent uranium ions in two isostructural, one-dimesional chains made up by aligned UM2 units, with M = Pt and...

We propose to measure the spin excitation spectrum in cuprate superconductor, La2-xSrxCuO4 (LSCO) at x=0.19. Our aim is to resolve the doping dependence of the 18 meV spin...

Here we propose to measure the phonon density of states in nanocrystalline samples of YAG:Cr. Our parallel luminscence measurements have revealed dramatic changes in the phonon...

Nanowires can be used for devices based on thermoelectrics and to convert the heat into electrical current. The material design challenge here is to create the materials where...

Our previous studies of the hole-doped antiferromagnet La1.75Sr0.25CoO4 have shown the distinctive "Hour-Glass" dispersion attributed to magnetic and charge ordered stripes....
