Springer Materials Science

The aim of this book is to acquaintthe reader with the phenomenon of sup- conductivity and the high temperature superconductors discovered in 1986 by Bednorz and Muller. Just after this discovery, a lot of research work was carried out by the scientists worldwide over for more than about 10 years. This book describes the superconductivity phenomenon (Chap. 1), the structureofhighT superconductors(Chap.2),thecriticalcurrents(Chap.3), c synthesis of high T superconductors (Chap. 3), the superconductivity in c cuprates (Chap. 4), proximity e?ect and SQUID devices, their design criteria and noise aspects (Chap. 6), theories (Chap. 7) and applications (Chap. 8).
