【発明の名称】イットリウム‐バリウム‐コバルト酸化物導電性組成物

Document Type and Number:

Japanese Patent JPH03503520

Kind Code:

A

Abstract:

Electrically conductive compositions have the formula AwBxCoyOz, where A is yttrium, samarium, or lanthanum; B is calcium, strontium, or barium, provided that B is barium if A is yttrium or samarium; and w is about 0.5 to about 1.5, x is about 1.5 to about 2.5, y is about 2.5 to about 3.5, and z is less than about 6.5. Further, they exhibit anomalies in their resistance and magnetic properties as a function of temperature. AB2Co3O3.5, particularly YBa2Co3O3.5, is preferred.
