Over the last forty years there has been an enormous international effort directed at increasing the upper critical field of superconducting materials because it determines the maximum magnetic field a magnet system can produce. High-energy particle accelerators and MRI body scanners are limited by the upper critical field for NbTi (10 T). Gigahertz class NMR and high field laboratory magnets are limited by the upper critical field for Nb3Sn ( 23 T). Recently we have fabricated disordered nanocrystalline bulk Chevrel phase Pbf.lo6S8 and Nb using mechanical milling and hotisostatic pressing. This process caused the upper critical field to increase in PbMo6S8 from 60 T to more than 100 T and in Nb from 0.4 T up to > 4T (the highest values reported for both of these materials). This pioneering work has demonstrated that disorder can be introduced at the nanoscale to substantially enhance the upper critical field in bulk samples. This proposal will support research in this new field. investigating the relationships between processing, structure and properties in a broad range of bulk disordered nanocrystalline and amorphous superconducting materials and hence improve understanding of the underlying science that produces these state-of-the-art high field properties.Over the last ten years, researchers in Durham have developed expertise and equipment to fabricate high purity superconducting materials and investigate their properties in high magnetic fields. We intend to lead the international research in this area and continue to improve the high field properties of superconductors. This will enhance the prospects of sustaining the existing magnet market, expand opportunities in design, engineering manufacture and testing and secure existing jobs in the U.K. superconductivity industry
