Title:
OXIDE SUPERCONDUCTOR THIN FILM ELEMENT
Document Type and Number:
WIPO Patent Application WO/2004/038816
Kind Code:
A1
Abstract:
An oxide superconductor thin film element which comprises a substrate and an oxide superconductor thin film, wherein the oxide superconductor thin film has a composition represented by Yb1-xNdxBa2Cu3O7-y where x is 0.01 to 0.30 and y is 0.00 to 0.20, and c axes of crystal grains thereof are oriented in a direction perpendicular to the substrate. The oxide superconductor thin film element has allowed the preparation of a thin film element which is free from problems associated with conventional superconductor thin film elements, mentioned in the specification, and exhibits excellent performance capabilities, with a low temperature of a substrate.
