Magnetic Properties of Rare-Earth Carbonates
We have prepared a new family of rare-earth carbonates, R4(CO3)6(H2O)2en (R=Dy-Lu). With the exception of R=Er, all materials exhibit a steadily decreasing meff below 70K. The... -
Order-Disorder Transitions in Layered Tellurides
We have prepared a new series of layered tellurides Cr2-xInxGe2Te6, containing 2D ordered arrays of (Cr,In) cations and (Ge-Ge) pairs. Recent neutron measurements reveal indium... -
High-Temperature Neutron Diffraction of Thermoelectric Materials
We wish to investigate the origin of the promising thermoelectic performance of oxy-chalcogenides BiOCuQ (Q = S, Se, Te) and related phases. We wish to explore whether the low... -

Structure and Magnetism in Iron-Substituted Benavidesite
We wish to investigate a new series of materials in which manganese in benavidesite, MnPb4Sb6S14, is progressively replaced by iron, leading to jamesonite at complete... -
Order-disorder transitions in ternary unfilled skutterudites
The aim of this proposal is to study the thermal evolution of the structure of two ternary ordered skutterudites, CoGe1.5Q1.5 (Q = S, Te). At room temperature, ordering of the... -
Magnetic Ordering in a Kagome-like Cobalt Sulphate
We have recently prepared a new cobalt sulphate, Co3(SO4)3(OH)2[enH2], under solvothermal conditions. The structure of this material consists of edge-sharing CoO6 octahedra that... -
Copy of: Structural and Magnetic Studies of Mixed-Valence Iron Silicates
We propose to study the temperature evolution of the spontaneous strain, crystal and magnetic structure of the charge ordered, mixed valence iron silicate ilvaite. In addition,... -
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... -
Cation Ordering and Magnetic Properties of Layered Tellurides
We have prepared a new non-stoichiometric series Cr2-xInxGe2Te6. X-ray diffraction data can be indexed on the rhombohedral unit cell of the end-member (x=0) phase. This adopts a... -
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... -
Diffraction Resistance Measurements of a Chalcopyrite
During the course of a PhD project funded by CCLRC's CMPC, we have developed a cell that allows electrical transport property measurements to be made simultaneously with the... -
Low-Temperature Structural Phase Transitions in GeV4S8
The defect thiospinel, GeV4S8 adopts a cubic structure at room temperature (space group F-43m). We have identified a new monoclinic phase of this material at 2K, which may be... -
Structure and cation ordering in A2Sn3Q7-type phases (A=In, Cr; Q= S, Se)
We wish to exploit the contrast afforded by neutrons to study the ordering of In and Sn cations in indium tin chalcogenides. Cation ordering has been inferred from spectroscopic...
