Title:
SUPERCONDUCTING WIRE AND ITS PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2005/015575
Kind Code:
A1
Abstract:
A superconducting wire (10) where a superconducting layer (3) is formed on a metal substrate which is an oriented metal substrate (1). The shift angle of the crystal axis from the orientation axis in the surface layer extending from the surface to the depth of 300 nm is 25° or less, and the surface is planarized to have a surface roughness RP-V of 150 nm or less. A method for producing such a superconducting wire is also disclosed. The superconducting wire has high superconduction performance thanks to the planarization of the oriented metal substrate while maintaining the biaxial orientation in the surface layer of the substrate.
