ABSTRACT:
A composite superconductor that comprises a first alloy selected from the class consisting of Nb-Sn-X, V-Ga-X, and V-Si-X wherein X is selected from the class consisting of yttrium, tellurium, lanthanum, cerium, gadolinium, erbium, and mixtures thereof and is in an amount up to 300% of the solubility limit of X in the alloy; a second alloy selected from the class consisting of Cu-Ga, Cu-Ga-Al, Cu-Su, and Cu-Si; and a continuous layer of an intermetallic A-15 compound between the alloys, the layer being formed by a solid state reaction between the alloys.
