The temperature dependence of the superconducting critical current density J/sub c/ and the upper critical field H/sub c/ has been studied for the composite-processed V/Hf/sub 0.4/Zr/sub 0.6/ tape, in which the C-15 crystal-type Laves phase compound is formed by diffusion between the vanadium sheath and the Hf/sub 0.4/Zr/sub 0.6/ alloy core. J/sub c/ of the V/Hf/sub 0.4/Zr/sub 0.6/ rapidly increases with decreasing temperature. At 1.7 K the V/Hf/sub 0.4/Zr/sub 0.6/ shows higher H/sub c/ and J/sub c/ than those of commercially available Nb/sub 3/Sn and V/sub 3/Ga. A superconducting magnet wound with V/Hf/sub 0.4/Zr/sub 0.6/ tape might be able to generate a magnetic field exceeding 200 kOe at 1.7 K. (AIP)
