Abstract : A multifilament composite superconductor which comprises (1) a matrix sheath selected from the group consisting of a copper-gallium (Cu-Ga) alloy with a gallium content from 0.4 to 22 at.%, a copper-tin (Cu-Sn) alloy with a tin content from 1 to 11 at.%, and a copper-silicon (Cu-Si) alloy with a silicon content from 0.5 to 14 at.%; (2) multiple filaments embedded in said encasing matrix sheath and selected from the class consisting of a vanadium -gallium (V-Ga) alloy with a gallium content from 0.4 at.% to 12.5 at.%, a niobium-tin (Nb-Sn) alloy with a tin content from 0.1 at.% to 12.0 at.%, and vanadium-silicon (V-Si) alloy with a silicon content from 0.5 to 10 at.%; and (3) a continuous interfacial layer between said matrix and each filament of an A-15 compound selected from the class consisting of V3Ga, Nb3Sn, and V3Si.
