Title:
A manufacturing method of superconducting wire material and superconducting wire material
Document Type and Number:
Japanese Patent JP5950826
Kind Code:
B2
Abstract:
Impurities in an oxide superconducting layer or at a surface of the oxide superconducting layer at an intermediate layer side are reduced. A superconducting wire rod has a configuration that includes a metal substrate 10; an intermediate layer 20 formed on the metal substrate 10 and containing a rare-earth element that reacts with Ba; a reaction suppressing layer 28 formed on the intermediate layer 20 and mainly containing LaMnO3+δ1, wherein δ1 represents an amount of non-stoichiometric oxygen; and an oxide superconducting layer 30 formed on the reaction suppressing layer 28 and mainly containing an oxide superconductor containing Ba.
