Abstract

The discovery of La-Ba-Cu-O superconductors by Bednorz & Müllerl has stimulated many investigators to study high-Tc oxide superconductors. Following the 40 K-class of superconductors with K2NiF4 structure2, the 90 K-class of oxygen-deficient perovskites3 was discovered, and very recently, superconductors of the Bi-Sr-Ca-Cu-O system, with an onset critical temperature of 120 K, have been reported. High-Tc superconducting oxides are complicated oxide systems. This paper aims to discuss high-Tc oxide superconductors from the viewpoint of defect chemistry.
