Research Facilities

The Superconductivity and Magnetism Group has a suite of state-of-the-art equipment that is operated and maintained by the Group. This apparatus is used for:

These facilities are available for use by members of the Department, the University, and, through collaborations, by external users.

If you would like to know more please contact a member of the Superconductivity and Magnetism Group (please see listings below).

During the course of our research work we also make regular use of a number of Central Facilities here in the UK and abroad.
