OXIDE SUPERCONDUCTIVE WIRE, SUPERCONDUCTIVE STRUCTURE, MANUFACTURING METHOD FOR OXIDE SUPERCONDUCTIVE WIRE, SUPERCONDUCTIVE CABLE, SUPERCONDUCTIVE MAGNET, AND PRODUCT INCLUDING SUPERCONDUCTIVE MAGNET

摘要

PROBLEM TO BE SOLVED: To provide an oxide superconductive wire making critical current density high and reducing AC loss, a superconductive structure, a manufacturing method for the oxide superconductive wire, a superconductive cable, a superconductive magnet and a product including the superconductive magnet. SOLUTION: The tape-like oxide superconductive wire is formed by embedding a plurality of filaments including a Bi-2223 oxide superconductor, in a matrix, wherein the cross-sectional area of a cross section orthogonal to the longitudinal direction of the oxide superconductive wire is 0.5 mm2or less, and the average cross-sectional area per filament in the cross section of the oxide superconductive wire is≥0.2% and≤6% of the cross-sectional area of the oxide superconductive wire.
