The response of the magnetic ordering of layered cobalt oxide chalcogenides to changes in electron count will be investigated in detail following a preliminary experiment at... -
High Pressure Behaviour of Benzene
The interactions between benzene molecules in the solid phase is of fundamental interest. Benzene is often used as a model system for structure prediction methodologies and... -
Forcing Sr2NiO2Cu2Se2 into the low spin regime under pressure
This is a proposal to drive the layered oxide chalcogenide Sr2NiO2Cu2Se2 from the high-spin state with long range magnetic order to the low-spin state, similar to that displayed... -
