Dispersionless spin waves and field-induced magnetic order in Gd3Al5O12
Gd3Ga5O12 (GGG) is the archetypal frustrated magnet with unusual short-range order and magnetic excitations. Recently we have found that the dominant contribution to INS in GGG... -
The partial dynamical structure factors and vibrational density of states in ...
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... -
Neutron diffraction of fully deuterated amorphous calcium phosphate (d-ACP)
Bone growth involves the formation of hydroxyapatite, HA, nanocrystals in the body. In vitro studies showed that HA does not precipitate directly, but that amorphous calcium... -
Neutron scattering investigation of spin-dynamics in the S= 1/2 trimer chain ...
Spin-trimer chain systems are of current interest due to unconventional properties arising from the strong quantum fluctuations and topology, such as, quantum phenomenon of... -

The Pressure and Temperature Dependence of the Structure of Ammonium Triiodide
We have shown that the molecular ionic solids MI3 (M=Tl, Cs, Tl, NH4) undergo structural phase transitions below 3.4 GPa at RT to give the same new high pressure phase (HP) with... -
The dynamics of the calcium-ammonia-graphite decomposition with hydrogen
Graphite intercalation compounds (GICs) have potential as hydrogen storage materials, from direct physisorption of H2 or as a high surface area nanostructured host for metal... -
Molecular and framework dynamics in CH3NH3PbBr3 - Raman and neutron scattering
Organic-inorganic perovskites have recently been shown to be potentially efficient and inexpensive photovoltaics. These materials undergo a series of structural transitions and... -
Study of a spin gap and CEF excitations in the caged compounds CeT2Al10 (T=Fe...
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... -
Study of vibron stability in CeCuxAl4-x with x = 0.95 and 1.05
CeCuxAl4-x compounds crystallize in the ordered non-centrosymmeric tetragonal BaNiSn3-type structure (space group 107, I4mm). The strong interaction between crystal field (CF)... -
Equation of state and phase transitions of the cubic NTE material Cd(CN)2
Despite being the material showing the largest isotropic NTE, Cd(CN)2 is remarkably little studied, particularly compared to isostructural Zn(CN)2 and the canonical NTE material... -

The application of INS to investigate the active phase of methane steam refor...
A previous allocation of beamtime on MAPS [RB720354] revealed the vibrational fingerprint of methane reforming catalysts operating under so-called ¿dry¿ reforming conditions.... -
Can we use the H-H stretch of adsorbed dihydrogen to characterise materials?
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... -
The role of zero-point fluctuations in a quantum-disordered spin-dimer compound
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... -
Nematic spin fluctuations in tetragonal La2-xSrxCuO4
Uniaxial stress has been used to study the Fe-based superconductors with spectacular results. Both the transport properties and the low-energy magnetic excitations have been... -
Alloxan - a high density organic under pressure
Organic molecular crystal structures have densities that are typically in the range 1.2-1.4 gcm-3 although these can be increased, in general, to ca. 2.0 GPa through application... -
Crystal Field Splitting in Dysprosium Double Decker Single Molecule Magnets
We aim to elucidate the low-energy electronic structure of two distinct dysprosium bisphthalocyanine single-molecule magnets by direct observation of crystal field excitations...
