Phonon-Liquid-Electron Crystal Behaviour in Cu8GeSe6
Thermoelectric devices enable the conversion of thermal energy into electrical power. The development of new materials is essential to enable large scale implementation of... -
How Encapsulated is a Sodide? Li+Na--EtNH2 vs Li+e--EtNH2
We have recently begun to look at how large, polarisable alkalides (group 1 metal anions) are solvated in solution. This proposal aims to determine how ethylamine is able to... -
Local structure study of Cr-Fe alloys with enhanced magnetovolume effect
Negative thermal expansion (NTE) materials, the volume of a material abnormally contract with the increase of temperature, is closed related to the magnetovolume effect in... -
Development of a Novel Low - Intermediate Temperature Solid Proton Conductor
The compound, Si5O(PO4)6, is a component of a solid phosphoric acid catalyst, it has highly unusual coordination of the silicon (octahedral, as well as the more common... -
Phase Transitons and Phonon-Liquid-Electron Crystal Behaviour in Argyrodites
We wish to collect powder neutron diffraction as a function of temperature on four samples of argyrodites, A8GeQ6 (A = Cu, Ag; Q = S, Se), to investigate structural phase... -
Colossal Magnetoresistance in PrBa2Cu3O7-d
Large negative bulk magnetoresistance has recently been observed in ruthenocuprate materials RuSr2R2-xCexCu2O10-d (up to -47 % at 5 K in a 9 T field). This material exhibits -MR... -
Structural and magnetic characterisation of polar magnetic perovskite-based m...
A new generation of low-power high-density information storage would be enabled by the development of ?multiferroic? materials which function at or above room temperature. Such... -
Structural Phase Diagram of the new Multiferroic Hexagonal YbFeO3
This experiment aims to map out the structural phase diagram of the new multiferroic compound hexagonal-YbFeO3 as a function of temperature, both above and below room... -
Towards an accurate structural phase diagram for the novel BiScO3-PbTiO3 ferr...
The aim of this experiment is to determine accurately the crystal structures of phases in the (1-x)BiScO3-xPbTiO3 (BST-PT) perovskite phase diagram, particularly in the vicinity... -
Anion disorder in Ti pyrochlores as a precursor in the transition to fluorite
The aim of this work is to understand the nature of anion disordering in pyrochlore oxides and to establish what, if any, correlations exist between the anion position, disorder... -
Investigating the graphitisation behaviour of polycrystalline diamond at high...
Polycrystalline diamond is a man-made diamond material used for rock drilling and machining operations. Its vastly superior hardness to any other material allows it to cut... -
Quantum-Critical Dynamics of a 3-dimensional Antiferromagnet
We have recently discovered a pressure-induced quantum phase transition (QPT) at 4.3 kbar in the gapped quantum magnet piperazinium hexachlorodicuprate (PHCC) by means of... -

The applicants seek 4 days of beam time on POLARIS to study the deammoniation process of synthesised M(NH3)6X2 (M=Mg, X=I, Cl, Br) which are an important class of materials for... -
Neutron diffraction experiments on an Etruscan vase
An antique vase from an Etruscan necropolis was made available for neutron-based experiments at ISIS. Preliminary studies on this sample have shown unusual features and opened... -
Crystal and magnetic structures of new ruthenate perovskites
Ruthenate perovskites have a diverse range of electronic properties originating from electron-electron correlations within broad 4d bands. We have recently investigated the high... -
The origin of high oxide-ion conductivity and the nature of the intermediate ...
4 days of beam time is requested on HRPD to study the crystal chemistry of the ferroelectric Aurivillius phase Bi4Ti3O12 (Curie Temperature, Tc ~ 675 C, mixed conductor) and a... -
Total scattering measurement of EMT framework zeolite: does it obey Lowenstei...
Zeolites are meso- and nano-porous framework materials with applications in many industries. The zeolite framework consists of corner-sharing tetrahedral units. The catalytic... -
