Membrane lipids of marine planktonic archaea have provided unique insights into archaeal ecology and paleoceanography. However, past studies of archaeal lipids in suspended...

URu2Si2 has been examined intensively over the decades for the rich phase diagram including superconductivity, Hidden Order and multiple magnetic phases appearing around the...

The Dzyaloshinskii-Moriya interaction is thought to be responsible for the stabilization of weak ferromagnetism or magnetic spiral states in a number of diverse systems. An...

The orthorhombic compound Ba4Ru3O10 having Ru3O12 timers coupled via corner-shared oxygens in the crystal structure exhibits very interesting magnetic and transport properties....

Liquid light and heavy water are the most widely used moderator and reflector materials in nuclear reactors, however there is a lack of knowledge of the vibrational density of...

We propose to study low-energy magnetic excitations associated with the low-temperature ordered phase in polycrystalline Sr2VO4. This layered perovskite compound exhibits an...

We propose to perform a neutron inelastic scattering study on the anisotropic triangular lattice system beta-NaMnO2. This work will be an extension of our previous study on...

Understanding the electronic anisotropic state at a temperature associated with the nematic phase is unresolved problems in iron pnictides. Although many experiments focus on...

The spin excitations in superconducting LiFeAs have been found evolved from incommensurate peaks to commensurate peak at low energy. But the spin resonance is still not clear in...

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...

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...

Sr2CuWO6 is a double perovskite at the border between two and three dimensional magnetism, with a square lattice of S=1⁄2 Cu(II) ions. This proposal aims to use inelastic...

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...

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...

Our neutron study using MARI/MERLIN on Ce(Ru1-xFex) 2Al10 reveals very interesting magnetic excitations and a manuscript is ready to submit to PRB. In x=0 (TN=27 K) a...

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...

We propose to study the powder averaged spin fluctuations in a S=5/2 pryochlore - FeF3. Previous studies, corroborated by our own diffraction work on WISH, have measured that...

We wish to measure the partial dynamical structure factors and the partial vibrational density of states (VDOS) for the archetypal network forming glass GeSe2 by using the...

Heisenberg antiferromagnetic (HAF) S = ½ chains are famous for their gapless magnetic excitation spectrum. Interestingly, in SrCuO2 and Sr2CuO3, which are some of the best...
