Flux Pinning in Superconductors

This book discusses the flux pinning mechanisms and properties in metallic, high-Tc, and MgB2 superconductors, including condensation energy and kinetic energy interactions, summation theories, irreversible magnetization, and AC loss. It also discusses the influence of flux pinning on the vortex phase diagram and the dependencies of the irreversibility field on other quantities. Recent developments in critical current properties are introduced. The book is aimed at graduate students and researchers studying superconductivity and engineers working in the electric utility industry.

This comprehensive book delves into the intricate mechanisms and properties of flux pinning in metallic, high-Tc, and MgB2 superconductors. It explores the electromagnetic phenomena caused by this common pinning phenomenon, shedding light on the underlying physics. The author introduces two key pinning mechanisms: the condensation energy interaction, known for normal precipitates or grain boundaries, and the kinetic energy interaction proposed for artificial Nb pins in Nb-Ti alloys, among others. Detailed summation theories are presented to derive the critical current density, a crucial parameter in superconductivity. Additionally, the book discusses irreversible magnetization and AC loss caused by flux pinning, originating from the ohmic dissipation of normal electrons in the normal core driven by the electric field induced by flux motion. The influence of flux pinning on the vortex phase diagram in high-Tc superconductors is explored, along with the dependencies of the irreversibility field on various quantities such as superconductor anisotropy, specimen size, and electric field strength.

The 3rd edition of this book has been extensively revised and updated, featuring a new chapter on the critical state model. The author delves into the detailed mechanism of irreversible properties, providing calculations of pinning loss using the equation of motion of flux lines in the pinning potential and hysteresis loss. Through this comprehensive exploration, readers will gain a deeper understanding of why the resultant loss exhibits hysteresis characteristics despite the underlying mechanism.

This book is designed to serve as a valuable resource for graduate students and researchers actively engaged in the field of superconductivity, as well as engineers working in the electric utility industry. It offers a comprehensive and up-to-date account of the latest developments in flux pinning, providing valuable insights into this critical aspect of superconductivity and its practical applications.
