Physical Properties of Unconventional Superconductors

Abstract

The introduction part of the book is devoted to the description of physical properties of advanced classes of superconductors: cuprate superconductors, borocarbides, magnesium diboride, and oxypnictides. Description of crystal structure, electronic properties, and related theoretical models for each group of superconductors is presented. Anisotropy and multiband effects are specially emphasized. Well-known and generally accepted results of computed Fermi surface of these compounds and Fermi liquid properties are included to first part. Results of order parameter symmetry, its relation with possible pairing mechanism, and general consequences for experimentally accessible properties investigations in this class of superconductors are presented. Different vortex states in advanced classes of superconductors and experimental results of related phenomena are also considered. The rich variety of superconducting compounds in the advanced class of superconductors and the growing knowledge of their electronic structure can be helpful to clarify differences and similarities with other exotic superconductors.
