Critical Currents, Proceedings of 6th INT Workshop, Cambridge 8-11 July 1991J. Evetts Like its predecessors, the 6th International Workshop on Critical Currents brought together many of the foremost researchers in this field for a dynamic exchange of views and information. The refereed papers from this exciting meeting have now been compiled in this volume so that all those with an interest in this important area of superconductivity can acquaint themselves with the latest developments. This book contains over 100 papers and the topics covered include the following: * pinning mechanisms * the critical state * magnetic phase diagrams * creep and flux flow * layer structures and granularity * fabrication and measurement techniques The papers presented here are reprinted from Superconductor Science and Technology (1992, Volume 5, Number 15), an Institute of Physics journal. |
