METHOD FOR MANUFACTURING SUPERCONDUCTING WIRE MATERIAL, AND SUPERCONDUCTING WIRE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2013/114588
Kind Code:
A1
Abstract:
Provided are a method for manufacturing a superconducting wire material in which the superconducting current is not saturated even when a superconducting layer is made into a thick film, and a superconducting wire material. A method for manufacturing a superconducting wire material (1) in which a superconducting layer (13) is formed on a metal substrate (11) interposed by an intermediate layer (12), wherein the method for manufacturing the superconducting wire material is characterized in including a heating step for heating the metal substrate (11) up to the film-formation temperature of a superconducting film for forming the superconducting layer (13), a film-formation step for forming a superconducting film having a film thickness of at least 10 nm and no more than 200 nm on the intermediate layer (12), and a cooling step for reducing the metal substrate (11) temperature to a level below the film-formation temperature of the superconducting film, the method also being characterized in that the superconducting film-formation steps, comprising the heating step, the film-formation step, and the cooling step, are performed a plurality of times.
