PERMANENT CURRENT SWITCH MATERIAL AND PRODUCTION METHOD THEREFOR

Title:

PERMANENT CURRENT SWITCH MATERIAL AND PRODUCTION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2003/028120

Kind Code:

A1

Abstract:

A permanent current switch which operates at operating temperatures higher than that of a metal−based superconducting wire, and which is smaller, lighter and higher in electric resistance in a normal conducting state than a superconducting Ag sheath wire. An LPE film formed in a meandering shape or a spiral shape for an elongated energizing route can fulfill the above requirements. The shape can be controlled by an LPE growth from a pre−processed seed film or by processing after a growth.
