ABSTRACT:
Method for preparing a superconducting thin film of compound oxide having improved properties on a substrate by laser evaporation technique. A target has a surface area which is smaller than an irradiation area of a spot of a laser beam used, so that whole surface of the surface is irradiated with the laser beam.
