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... -
Magnetic Excitation Spectrum of the Frustrated Antiferromagnet SrYb2O4
In SrYb2O4 the magnetic Yb3+ ions form sub-lattices of double chains running parallel to the crystallographic c-axis with frustrated first and second neighbour antiferromagnetic... -
Spin Glass to Canted Antiferromagnetism in Pseudo-dipolar Pyrochlores
Magnetic frustration is of topical interest due to the functional applications within the next generation of electronics. Pyrochlores have contributed significantly within this... -
Neutron Diffraction Analysis of the Crystallography of Early Scientific Instr...
Early scientific instruments are typically made of latten, a quaternary copper alloy (Cu, Zn, Sn, Pb) with many trace elements. The crystallographic structure depends on the... -
Structure of amorphous Porous Aromatic Framework 1
Materials that are porous at the atomic scale have proven to be important for many applications, including gas capture and catalysis. Recently it has become possible to make... -
Hydrogen Release Systems: MX2.(NH3)n (M=Mg, X=Cl) with LiH and MgH2
The applicants seek 3 days of beam time on POLARIS to study hydrogen release systems comprising M(NH3)6X2 (M=Mg, X=Cl) coupled with LiH and MgH. Mg(NH3)6Cl2 is an important... -
Magnon decay below the critical field in the S=1/2 Heisenberg antiferromagnet...
The two dimensional Heisenberg antiferromagnet on a square lattice is one of the most studied model quantum magnets. This is in part due to its intrinsic interest but also to... -
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... -
Round Robin on TOF Texture Analysis: ENGIN-X
In view of advances in texture research at pulsed neutron sources, we propose that ISIS participates in a 'Texture Round Robin' to benchmark the existing texture analysis... -
Giant magnetostriction in CoMnSi: a tricritical metamagnet with large changes...
For several years, we have been studying the thermodynamics of the metamagnetic phase transition in CoMnSi and substituted versions. Our motivation has been that the... -
