Thermoelectric (TE) materials are set to play an increasingly important role in the development of new energy efficient technologies by generating electrical current from waste... -
The partial dynamical structure factors and vibrational density of states in ...
The object of this proposal is to measure the partial dynamical structure factors and the partial vibrational density of states (VDOS) for the archetypal network forming glass... -
Magnetic inelastic scattering from dimethylammonium metal formates
The dimethylammonium metal formates (metal = Mn, Fe, Co, Ni) are metal-organic perovskite analogues of interest for potential multiferroicity. In these materials, electric... -
Dynamical Transitions in the Ogg Glasses
We request 4 days on IRIS to study the temperature dependance of the structural dynamics in amorphous sodium-ammonia (Na-NH3). This will be the first investigation of the... -

Spin dynamics of pressure-induced heavy fermion superconductor CeRhGe2
The discovery of unconventional superconductivity (SC) in several heavy fermion (HF) compounds has attracted considerable attention. Recently we have investigated CeTSi3 (T=Rh... -
Spin excitations of detwinned BaFe2As2
Although spin excitations in BaFe2As2 are thought spin-wave excitations and the excitation will locate at antiferromagnetic vector (1 0) only for a detwinned sample, the real... -
Topotactically reduced phases containing square planar Co(II) centres
The topotactic reduction of Sr3Co2O5Cl2 and Sr3Co2O5.80 yields the Co(II) phases Sr3Co2O4Cl2 and Sr3Co2O5 respectively. These phases contain corner linked arrays of... -
Neutron scattering and muSR studies of magnetic phenomena in YFe2Al10: case s...
In strongly correlated electron systems, the proximity to magnetic ordering has been of special interest. Magnetism in this class of systems is often suppressed by the Kondo... -
Dy3Mg2Sb3O14 - a 2D Kagome lattice with Classical Ising Spins
Dy3Mg2Sb3O14 forms a layered structure with magnetic Dy3+ ions forming sheets of corner sharing triangles, called a Kagome lattice. The Ising magnetic moments are constrained to... -
Structure of beta-Mo2N in the normal and superconducting states; an in-situ r...
A recent experiment (RB820171) unexpectedly revealed that a sample of beta-Mo2N exhibited a number of extra reflections at 4 K; a temperature below the superconducting critical... -
Vacancy clusters and local magnetic structure of wüstite, Fe(1-x)O
The nature and distribution of vacancy defects in wüstite, Fe(1-x)O, is an important problem because the structural and dynamical properties of the mineral - both of which are... -
Magnetic excitations in the S=1/2 ferromagnetic semiconductor Lu2V2O7
Lu2V2O7 is a rare example of an S=1/2 pyrochlore. The fact that it is a ferromagnet with Tc=70 K belies the fact that it has some truly remarkable properties. These include the... -
Excitation spectrum of the frustrated spinel GeCo2O4
The spinel GeCo2O4 is a promising compound to establish the consequences of geometrical frustration, as the magnetic Co2+ ions are on a network of corner-sharing tetrahedra... -

This proposal seeks to measure the poly-CINS (polycrystalline coherent inelastic neutron scattering) spectrum from magnesium deuteride (MgD2); a powder sample on the MARI... -
Spin excitations in the superconducting FeTe0.6Se0.4
The FeTe1-xSex series exhibits superconductivity over a broad range of doping. Previously we have made extensive neutron scattering measurements on superconducting x = 0.49 and... -
Inelastic neutron scattering study of spin gap formation in two forms of BaRuO3
Pseudogap phenomena, which are associated with the reduction in the density of states at EF, have been intensively investigated in HTSC, as well in heavy fermion systems through...
