Iron-based superconductors

The new iron age: a newly discovered family of superconductors offers a fresh chance to understand unconventional superconductivity.

A new family of superconductors have been discovered which are based on iron. These are very surprising materials because the magnetism in iron is normally believed to preclude superconductivity and so iron-based compounds were not thought to be likely candidate superconductors. The new iron arsenides have remarkably high transition temperatures and have become a very hot topic for study.

Work in Oxford concentrates on studying these new superconductors using neutrons, muons and fermiological techniques. We have a particularly fruitful colllaboration with the group of Simon Clarke in Inorganic Chemistry.
