Multiferroic (Ferroelastic/Magnetic) Phase Transitions in KMnF3
KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling... -
Metal distributions in materials with the shandite structure, Co3Sn2-xInxS2 (...
The aim of this proposal, which is part of a PhD project, is to investigate ordering of In and Sn in the solid solution Co3Sn2-xInxS2 (0<=x<=2). All members of this family... -

Doping Dependence of the Resonant Spin Excitation in Ba1-xKxFe2As2
We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the... -
Magnetic Excitations of a Model Quantum Spin Ladder
(C5H12N)2CuBr4 is the best realisation found to date of an antiferromagnetic quantum spin ladder in the strong coupling limit. This system displays an extremely rich phase... -
Magnetic Excitations in Chromium
Chromium is unique amongst the d-band elemental metals in that it has a spin density wave ground state. The spin density wave is caused by Fermi surface nesting between electron... -
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... -
Thermal expansion and simultaneous Raman spectroscopy of methanol ammoniates,...
We have recently determined the structures of methanol-monoammoniate, and Me-hemiammoniate from neutron powder data. These are found to have different degrees of C-H...O... -
Neutron analysis of the structure of SrAl2O4 from 300 to 1273 K.
SrAl2O4 is a stuffed tridymite that has attracted a good deal of interest, since doping with Eu2+ leads to a material with elastic-luminescent response. The structure and phase... -
Structural studies of the KSbO3-type osmates Sr6Os6O19 and Bi3Os3O11
Osmium-based oxides show a wide range of interesting properties due to the variety of oxidation states osmium can adopt combined with 5d electrons displaying strong spin-orbit... -
Structural distortions and partial order in the selenate and chromate analogu...
The mineral mirabilite (di-sodium sulfate decahydrate) has been extensively studied by X-ray and neutron powder and single-crystal diffraction methods. The structure contains an... -
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... -
High resolution studies of P2-type sodium ion battery cathode materials
