SUPERCONDUCTING THIN FILM MATERIAL AND METHOD FOR PRODUCING THE SAME

摘要

A superconducting thin film material (1) that can realize attainment of an excellent property such as a high J C and a high I C and reduction of costs at the same time includes an orientated metal substrate (10) and an oxide superconductor film (30) formed on the orientated metal substrate (10). The oxide superconductor film (30) includes a physical vapor deposition HoBCO layer (31) formed by a physical vapor deposition method, and a metal organic deposition HoBCO layer (32) formed on the physical vapor deposition HoBCO layer (31) by a metal organic deposition method.
