High-Temperature Superconducting Materials Science and Engineering

New Concepts and Technology

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

Audience
For technical non-specialists and graduate students in physics and materials science.
