All known iron-based superconductors comprise layers of FeAs or FeSe with some combination of group I, group II or lanthanide oxide layers, and usually some doping. To make...

Preliminary measurements of [FeFe]-hydrogenase model complexes were made in a previous experiment using EMU (RB 1010177). The results were interpreted in combination with DFT...

We propose to use OSIRIS to determine the magnetic structures of a series of cobalt oxysulfides containing Co in square planar coordination. Several compositions...

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...

Traditional high-temperature synthesis techniques can be used to vary the composition of K{1-x}Fe{2-y}Se2 up to certain limits. We have found a way to extend the limits on the K...

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...

Spin ladders present a class of low-dimensional quantum magnets that occupy a regime of rather subtle behavior which lies between the stark extremes of a one-dimensional chain...

In this work, we will investigate the structures (crystallographic and magnetic) of Mn5VO8 and a range of Fe containing perovskite oxide fluorides. In terms of the former, this...

In this experiment we will determine the detailed structure of the 6 K superconductor LiFeP and phases close in composition which are iron rich: Li1-xFe1+xP. This will enable...

This proposal requests neutron diffraction beamtime to study a series of novel metal fluorophosphates and acid pyrophosphates with potential as ionic conductors....

The reversible interconversion of protons and dihydrogen is an electrochemical process of fundamental importance to a hydrogen economy. The process requires catalysis to proceed...

Our previous studies of superconducting LiFeAs derivatives revealed a significant difference in Uemura scaling compared with all other studied pnictides. This experiment is...

We will use POLARIS to determine the structures of the high temperature superconducting intercalates obtained by the reactions between FeSe and deuterated ammonia solutions...

We have a continuing interest in the structural role of lone-pair cations in glasses. Thallium oxide behaves unusually in borate glasses, not only in terms of its own...

During our recent experiment (RB1310434) we were able to use ALC to characterise the radical states formed in [Fe2(µ-pdt)(CO)4(PMe3)2] and [Fe2(µ-pdt)(CO)4(CN)2]2- at two...

Through low temperature fluorination of AFeO3-x (A=Sr, Ba) it is possible to prepare the oxide fluorides AFeO2F, which are antiferromagnetically ordered at room temperature. In...

The purpose of this experiment is to gather structural data on the electron-doped derivatives of LiFeAs obtained by substituting some Fe by Co or Ni. In particular these data...

Metal-doped TiO2 have particular applications as in catalysis of a range of reactions as well as in luminescence materials. Our strategy is to make well-defined molecular TixOy...

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...

Two molecular magnetic systems are considered which show low-temperature ordered states. One of them is F4BImNN, a nitronyl nitroxide radical magnet, an excellent realization of...
