Superconductivity is one of the most interesting important and dynamic areas in science. The group in Durham has research activities in fabrication, measurement, theoretical calculations and computational work. The group has some of the best high magnetic field facilities of any University group in the world. Recent research highlights include: the discovery of a new class of nanocrystalline materials with exceptionally good tolerance to magnetic fields; the design, in-house fabrication, development and operation of variable strain instruments for measuring the strain and temperature dependence of the critical current in high magnetic fields; development of a new theoretical strain scaling law which successfully combines phenomenological and microscopic theory; the first visualisation of flux-flow in polycrystalline materials in high magnetic fields. We have strong collaborations with colleagues on the continent, and with groups in the USA and Japan working on high-field superconductors.
