  • Low alternating-current loss oxide superconductor and fabricating method thereof
    Patent number: 8880135
    Abstract: The present invention is configured such that, in a low AC loss oxide superconductor constituted by providing an oxide superconducting layer 6 on a substrate 1, said oxide superconducting layer 6 is separated into a plurality of filament conductors 2 in parallel to the lengthwise direction of said substrate 1 by dividing grooves 3 plurally formed in the widthwise direction of said substrate, and a high-resistance oxide 8 is formed in said dividing grooves 3. Because of the invention, it is possible to increase the insulation properties of individually divided mated filament conductors, and to obtain an oxide superconductor that has low AC loss.
    Type: Grant
