Title: Advances in Superconductivity IV
Description: This proceedings contains the latest topics on superconductivity in material science and technology, with special emphasis on research and development in the field of high-Tc superconductors. The contributions were collected at the 4th International Symposium on Superconductivity held in Tokyo, Japan, from October 14th - 17th, 1991. The contents focus on the following fields: Physics, Chemistry, Flux Pinning, Wires, Tapes, and Bulks, Thin Films, and Applications. As well as summarizing annual progress in these fields, the proceedings is organized to serve as avenue for increasing understanding of superconductivity and for exchanging visions for future research and applications.
