Title:
PROCESS FOR PRODUCING SUPERCONDUCTING THIN-FILM MATERIAL, SUPERCONDUCTING EQUIPMENT AND SUPERCONDUCTING THIN-FILM MATERIAL
Document Type and Number:
WIPO Patent Application WO/2007/094147
Kind Code:
A1
Abstract:
A process for producing a superconducting thin-film material, including the steps of forming interlayer (2); forming superconducting layer (3) abutting on the interlayer (2); and forming superconducting layer (4) abutting on the superconducting layer (3) in accordance with a vapor phase method. The interlayer (2) is retained in a reduced-steam atmosphere or reduced-carbon-dioxide atmosphere during the period between the interlayer (2) forming step and the superconducting layer (3) forming step. The superconducting layer (3) is retained in a reduced-steam atmosphere or reduced-carbon-dioxide atmosphere during the period between the superconducting layer (3) forming step and the superconducting layer (4) forming step. Accordingly, the value of critical current can be enhanced.
