Title:
SUBSTRATE FOR SUPER-CONDUCTIVE FILM FORMATION, SUPER-CONDUCTIVE WIRE MATERIAL, AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2010/058823
Kind Code:
A1
Abstract:
Provided is a substrate for super-conductive film formation.  The substrate comprises a metal substrate and, formed directly on top of the metal substrate, an oxide layer of primarily chromium oxide having a layer thickness of 10 to 300 nm and a surface smoothness Ra of 50 nm or less.  Also provided is a method for producing a substrate for super-conductive film formation, comprising a step for forming an oxide layer, which has a layer thickness of 10 to 300 nm and a surface smoothness Ra of 50 nm or less, directly on top of a metal substrate.
