Crystal structures and properties of superconducting materials I

Abstract

Abstract Many excellent articles and textbooks on superconductivity have been published. However, concise and easily-handled data books written for scientists and engineers who work in the field of superconducting materials are very few. This article aims to collect and outline basic properties of superconducting materials and to provide such people with a database. The properties listed include crystal and electronic structures, equilibrium phase diagram, superconducting critical temperature, critical magnetic fields, critical current density, pinning force, specific heat coefficient, Debye temperature, penetration depth, coherence length, GL parameter, energy gap, electronic density of states at the Fermi level, electron-phonon coupling constant, Coulomb pseudopotential, and others. Emphasis is on the materials used in superconductive applications. Structural phase transitions such as martensitic transformations and transitions to the charge-density-wave state in superconducting materials are also revie...
