Title:
SUPERCONDUCTING WIRE MATERIAL AND SUPERCONDUCTING COIL
Document Type and Number:
WIPO Patent Application WO/2023/027149
Kind Code:
A1
Abstract:
This superconducting wire material comprises: a superconducting layered body that has a metal substrate and an oxide superconducting layer; and a stabilizing part which is formed so as to cover the superconducting layered body and which has a larger coefficient of thermal expansion than the metal substrate. The superconducting layered body includes: a first primary surface that is a surface on the side on which the oxide superconducting layer is provided; and a second primary surface that is a surface on the side on which the metal substrate is provided. The stabilizing part includes: a first section which faces the first primary surface; and a second section which faces the second primary surface. The thickness of the second section is greater than the thickness of the first section.
