Abstract
Abstract A superconducting wire containing a multifilamentary superconducting alloy, comprising at least one composite containing a first matrix in which a plurality of superconducting alloy filaments have been arranged and a second matrix in which at least one composite is embedded; wherein said first matrix consists essentially of a metal or an alloy which does not form any intermetallic compound with the superconducting alloy filament. As the superconducting alloy filament, a Nb-Ti alloy filament may preferably be selected; the first matrix may preferably consist of one selected from the group of Nb, Ta and a Nb-Ta alloy; and the second matrix may preferably consist of Cu, A Cu-Ni alloy, Al, or an Al alloy.
