ABSTRACT:
An oxide is formed which will form an oxide superconductor containing a Cu-O atomic layer. The oxide is hydrogenated. The oxide is oxidized after it is hydrogenated. The hydrogenation and the oxidization are executed simultaneously with or after the oxide is formed. The hydrogenation and the oxidization improve the superconducting characteristics of the oxide superconductor.
