The Nb/sub 3/Sn growth rate H/sub c/2 and J/sub c/ in high fields (> or =12 T) of composite-processed Nb/sub 3/Sn are greatly increased by the addition of hafnium to the niobium core. Furthermore, the simultaneous addition of hafnium to the core and gallium to the matrix more significantly enhances H/sub c/2, and J/sub c/ in high fields. J/sub c/ of the Nb-Hf/Cu-Sn-Ga wire specimens exceeds 1 x 10/sup 5/ A/cm/sup 2/ at 17 T, suggesting the possibility of fabricating multifilamentary Nb/sub 3/Sn composite wires that stand use in fields at least up to 17 T.
