PROCESS FOR PRODUCING SUPERCONDUCTING THIN-FILM MATERIAL, SUPERCONDUCTING EQUIPMENT AND SUPERCONDUCTING THIN-FILM MATERIAL

WIPO Patent Application WO/2007/094146

A1

A process for producing a superconducting thin-film material, including the vapor phase step of forming superconducting layer (3) in accordance with a vapor phase method and the liquid phase step of forming superconducting layer (4) abutting on the superconducting layer (3) in accordance with a liquid phase method. Preferably, the process further includes the step of forming interlayer (2) between the superconducting layer (3) and metal substratum (1). It is preferred that the metal substratum (1) consist of a metal, and that the interlayer (2) consist of an oxide with any of rock, perovskite and pyrochlore crystal structures, and that both the superconducting layer (3) and the superconducting layer (4) have an RE123 composition. Accordingly, the value of critical current can be enhanced.
