This proposal was submitted on MERLIN (RB1010206) and beam time was allocated on MARI. We have carried out low energy measurements on MARI and found a clear evidence of the spin...

We propose to map out magnetic and lattice excitations in compounds Mn(5-x)Fe(x)Si3.Varying the Fe content, the system shows a tunable magneto-caloric effect, both in the...

We propose to investigate the magnetic fluctuations in a charge ordered magnet. Rb(Fe2+Fe3+)F6 is loosely based on a distorted Kagome framework with alternating chains of...

In everyday life, we often experience frustration from not being able to reach our goals; similarly, in physics and chemistry, frustration is caused by the inability of a system...

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...

The use of the J 0-to-1 rotational transition of dihydrogen has been extensively used to characterise the state if hydrogen in and on materials. The disadvantage of studying the...

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...

This proposal aims to investigate and compare the dynamics of CO2 when confined in a nanoporous Vycor (SiO2) matrix. The field of fluids in confined geometries is currently of...

Linarite is a natural mineral which displays a rich and complex phase diagram in applied fields up to 10 T for temperatures below 2.8 K. As a frustrated J1-J2 chain material,...

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

Na2Ti2Sb2O has a CDW transition around 120 K . It has a tetragonal structure with alternate layers of Ti2Sb2O2- and Na+ double layer. Interestingly, the Ba1-xNaxTi2Sb2O system...

NaxFe1/2Mn1/2O2 has been identified as a potential cathode material for Na-ion batteries since it has comparable electrochemical performance to commercially available Li-ion...

We propose to investigate the magnetic excitation spectra in the three accessible magnetic ordered phases of the quasi-1D S-1/2 Ising-like antiferromagnet SrCo2V2O8 by single...

In this proposal, we would like to suggest inelastic neutron scattering measurement on a single-crystal sample of a frustrated antiferromagnet CuFeO2 under applied magnetic...

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...

Sr2IrO4 is an important material in condensed matter physics, having been discovered to host a novel Jeff=½ Mott insulating state.Yet while magnetic fluctuations play a crucial...

The pyrochlores provide an excellent model system for studying the interaction of framework vibrational modes, defects and magnetism. We propose to investigate these couplings...

The growth in both global demand for energy and fossil-fuel related environmental issues drive research on alternative fuel sources. Solid oxide fuel cells, which can operate on...

We propose to measure the high energy magnon spectrum of Bi2Fe4O9 in order to finalize a spin wave model and to classify this compound within the theoretical phase diagram of...

The proposal aims to measure the powder averaged magnetic excitations in KFe2Se3. The compound is related to the recently discovered Fe-Se,As superconductors and is based upon...
