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 alkalline earth metal and copper respectively. Then the superimposed thin film is fired to convert to a superconducting film.
