Title:
METHOD OF FORMING SUPERCONDUCTING FILMS
Document Type and Number:
WIPO Patent Application WO/2003/012888
Kind Code:
A1
Abstract:
A method of forming superconducting films, comprising the steps of forming a conductive film on the surface of a substrate, using a solution in which oxide superconducting fine particles and non−superconducting fine particles for introducing a magnetic flux pinning center into a superconducting film are dispersed to migration−electrodepositing the high−temperature superconducting fine particles and the non−superconducting fine particles on the conductive film, and heat treating the substrate to sinter the superconducting fine particles and the non−superconducting fine particles and form a magnetic flux pinning center−introduced superconducting film.
