High Temperature Superconductors : Processing and Science
After six years of one of the most concentrated worldwide research efforts devoted to a single material, high-temperature superconductors are now entering the market as useful products. This book provides an introduction to superconductivity, with an emphasis on the state-of-the-art methods used to process these complex materials. The coverage is complete, with chapters on characterization and applications - both achievable and realized. Through a concise and unified distillation of disparate journal articles and reviews, this book provides a useful handbook for students and researchers alike. "High Temperature Superconductors: Processing and Science" may be used as a textbook in advanced ceramics and materials science courses; it will also appeal to physicists and chemists who are involved in the synthesis of compounds and specimens, as well as to engineers and applied scientists looking for ways to utilize these remarkable materials.
