Superconductivity and magnetism in iron-arsenide superconductors
The The recent discovery of superconductivity in FeAs-containing compounds (often known as the pnictides has provided a great stimulus to experiment and theory in the study of... -
Structural studies of Fe-pnictide superconductors using neutron total scattering
The recent discovery of superconductivity in a series of iron pnictide materials has led to the anticipation that they might lead to new insights into the origins of... -
Control of the electronic state in new pnictide superconductors using doping
The properties of pnictide superconductors can be controlled exquisitely by chemical doping. We have identified some key systems in which to explore this effect which should... -
Muon spin rotation study of LixFeyAs and NaFeAs superconductors
We will examine the magnetic and superconducting properties of these two novel superconducting systems using muon spin rotation and relaxation experiments. Stoichiometric LiFeAs... -
Superconductivity and magnetism in novel iron-based superconductors
Magnetism and superconductivity compete and coexist in many of the high temperature superconductors, and the newly discovered iron arsenides are no exception. Muon-spin rotation... -
Search for magnetic correlations in Fe phosphide superconductors
We propose to use inelastic neutron scattering to search for the existence of spin fluctuations in two iron phosphide superconductors, (La,Ca)FePO and Sr2ScFePO3. The objective... -
Fluorine-arsenide superconductors
A new family of FeAs superconductors have very recently (Autumn 2008) been discovered in which, rather than alternating rare earth oxide layers with FeAs layers (as for the new... -

The recent discovery of superconductivity in a series of iron pnictide materials has provided impetus to the field of new materials discovery. Like in the cuprate... -
Controlling superfluid stiffness and Tc in new pnictide superconductors
Our previous studies of superconducting LiFeAs derivatives revealed a significant difference in Uemura scaling compared with all other studied pnictides. This experiment is... -

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... -

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...
