Title:
HIGH-TEMPERATURE SUPERCONDUCTING WIRE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2022/158413
Kind Code:
A1
Abstract:
A purpose of the present invention is to provide a high-temperature superconducting wire material having a high critical current and low hysteresis loss. The high-temperature superconducting wire material that achieves this purpose has an elongated first metal substrate, and a plurality of filament wires arranged on the first metal substrate so as to extend in a longitudinal direction of the first metal substrate. The plurality of filament wires are arranged approximately in parallel with gaps therebetween, and each filament wire includes, in order from the first metal substrate side, a first superconducting layer containing a rare earth element, a first stabilizing layer, a second stabilizing layer, and a second superconducting layer containing a rare earth element.
