Progress of research of high-T(sub c) superconductors

Abstract

The research of high T(sub c) superconductors has made big progress in these last few years. New materials were found and the systematic investigations of these materials must contribute to understanding the mechanism of high T(sub c) superconductivity. The critical currents in thin films, bulks and tapes increased drastically, and the origin of flux pinning will be clarified in the near future. These progressions gives a view of a bright future of high T(sub c) superconductivity in both the basic and application research areas. Recent activities in research of high T(sub c) superconductivity and superconductors in Japan are overviewed
