ABSTRACT:
A copper substrate is immersed into a solution in which a Y-Ba-Cu-O series oxide superconducting fine powder is dispersed into an acetone solution and an electric field is applied thereto. A coating deposited on the copper substrate by electrophoresis is sintered with high temperature in vacuum or in an inert gas atmosphere and then subjected to heat-treatment for oxygen composition ratio in an atmosphere of oxygen or air under 500.degree. C. This method prevents occurrence of a CuO layer, which would conventionally be formed at an interface between a Y-Ba-Cu-O film and a Cu substrate disadvantageously, and moreover enables fabrication of superconducting coatings having satisfactory characteristics.
