ABSTRACT:
An improved method of manufacturing superconducting ceramics in the form of a thin film are described. The thin film is first formed of a superimposed structure composed of three films which contain a rare earth metal, an alkaline metal and copper respectively. Then the superimposed thin film is fired to convert to superconducting film.
