Microstructure And Properties Of High Temperature Superconductors

This book provides a comprehensive presentation of all types of HTSC and includes a broad overview on HTSC computer simulations and modeling. Especial attention is devoted to the Bi-Sr-Ca-Cu-O and Y-Ba-Cu-O families that today are the most perspective for applications. The book includes a great number of illustrations and references. The monograph is addressed to students, post-graduate students and specialists, taking part in the development, preparation and researching of new materials.

The main features of high-temperature superconductors (HTSC) that define their properties are intrinsic brittleness of oxide cuprates, the layered anisotropic structure and the supershort coherence length. Taking into account these features, this treatise presents research into HTSC microstructure and properties, and also explores the possibilities of optimization of the preparation techniques and superconducting compositions. The "composition-technique-experiment-theory-model," employed here, assumes considerable HTSC defectiveness and structure heterogeneity and helps to draw a comprehensive picture of modern representations of the microstructure, strength and the related structure-sensitive properties of the materials considered. Special attention is devoted to the Bi-Sr-Ca-Cu-O and Y-Ba-Cu-O families, which currently offer the most promising applications. Including a great number of illustrations and references, this monograph addresses students, post-graduate students and specialists, taking part in the development, preparation and research of new materials. The new edition had been updated intensively, especially experimental investigations and modeling conductive and elastic properties of HTC superconductors have been added.

The second in a series of books devoted to the title subject, this one reviewing some major areas of activity not covered extensively in volume 1 (1988): structure, microstructure, thermodynamics, oxygen stoichiometry effects, nuclear magnetic and quadruple resonance, transport of charge and heat, photoemission, microwave properties, films, and the pairing state.

This book provides an extensive introduction to the microstructures and structural defects in high-temperature superconductors. It illustrates the application of modern experimental techniques as well as theoretical modeling tools in the study of these complex materials. The readers are given an overview of the structure-sensitive properties, such as transport properties, and the effort to develop large-scale (high-current, high-field) applications for these materials. The effects of defects on the superconducting properties of these materials are described when feasible to put the study of microstructures in proper perspective.

This volume brings the reader up to date on transport phenomena, including electrical and thermal conductivity and infrared properties. In addition, electron tunneling and the characteristics and applications of films are discussed; the preparation of the necessary samples has proceeded, and a sizeable body of reproducible data has become available. Pressure effects are also presented; considerable progress has been made in relating them to the crystallographic and electronic structure of high temperature superconductors. The preparation and characterization of bulk samples is also reviewed.

This book explores the fascinating field of high-temperature superconductivity. Basic concepts–including experimental techniques and theoretical issues–are discussed in a clear, systematic manner. In addition, the most recent research results in the measurements, materials synthesis and processing, and characterization of physical properties of high-temperature superconductors are presented. Researchers and students alike can use this book as a comprehensive introduction not only to superconductivity but also to materials-related research in electromagnetic ceramics. Special features of the book: presents recent developments in vortex-state properties, defects characterization, and phase equilibrium introduces basic concepts for experimental techniques at low temperatures and high magnetic fields provides a valuable reference for materials-related research discusses potential industrial applications of high-temperature superconductivity includes novel processing technologies for thin film and bulk materials suggests areas of research and specific problems whose solution can make high-Tc superconductors a practical reality

In contrast to research on the fundamental mechanisms of High-Temperature Superconductivity, in recent years we have seen enormous developments in the fabrication and application of High-Tc-superconductors. The two volumes of High Temperature Superconductivity provide a survey of the state of the technology and engineering applications of these materials. They comprise extended original research papers and technical review articles written by physicists, chemists, materials scientists and engineers, all of them noted experts in their fields. The interdisciplinary and strictly application-oriented coverage should benefit graduate students and academic researchers in the mentioned areas as well as industrial experts. Volume 1 "Materials" focuses on major technical advancements in High-Tc materials processing for applications. Volume 2 "Engineering Applications" covers numerous application areas where High-Tc superconductors are making tremendous impact.
