Structural Aspects and Magnetic Order in Fe based perovskite oxide fluorides ...
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... -
Field induced spin Luttinger liquid phase in a spin ladder
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... -
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... -
Soft chemistry tuning between magnetism and superconductivity in K{1-x}Fe{2-y...
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... -
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 OSIRIS to determine the magnetic structures of a series of cobalt oxysulfides containing Co in square planar coordination. Several compositions... -
Artificial [FeFe]-Hydrogenases and Muon Spectroscopy
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... -
Iron-based superconductors with molecular spacer layers: probing Li diffusion...
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...
