Magnetism, structure and superconductivity in Sr1¿xNaxFe2As2 (HRPD)
We will use the high resolution of HRPD and the excellent long d-spacing data available on OSIRIS to investigate the phase transitions in Sr1-xNaxFe2As2 which are associated... -
Evolution of the structure of the Li/ND3 intercalate of FeSe with pressure
This experiment follows our ambient pressure characterisation of the Li intercalate of FeSe which is a superconductor with a Tc of 43 K. Li atoms, amide ions and ammonia... -
Resolving the structures of metal/ammonia intercalates of FeSe
This is a proposal to fully characterise the crystal structures of the superconducting metal/ammonia intercalates of FeSe made using low temperature methods. In particular we... -
Structures and Chemistry of new layered oxychalcogenides
We propose to use POLARIS to obtain detailed structural information on a series of new lithium-containing layered oxychalcogenides and to investigate the ordering of lithium... -
Structures of the superconducting metal/ammonia intercalates of FeSe
We will use POLARIS to determine the structures of the high temperature superconducting intercalates obtained by the reactions between FeSe and deuterated ammonia solutions... -
Search for magnetic fluctuations and a spin resonance in FeSe intercalated wi...
Very recently, bulk superconductivity has been found at Tc = 43 K in the layered compound FeSe intercalated with Li ions and amide and ammonia molecular groups. We propose to... -
Probing superconductivity, static magnetism and light ion diffusion in molecu...
In 2012 we demonstrated that molecular spacer layers could be intercalated in between FeSe layers resulting in a dramatic enhancement of the critical temperature: FeSe is itself... -
Magnetism, structure and superconductivity in Sr1¿xNaxFe2As2 (OSIRIS)
We will use the high resolution of HRPD and the excellent long d-spacing data available on OSIRIS to investigate the phase transitions in Sr1-xNaxFe2As2 which are associated... -
Correlation of structure and magnetic ordering with composition in layered co...
We propose to use HRPD to determine the detailed structures of a series of cobalt oxysulfides containing Co in square planar coordination. Two compositions Sr2CoO2Cu2-deltaS2...
