Description
The superconducting properties (T/sub c/ and J/sub c/) were investigated by the resistivity measurement, and the structure was observed by a transmission electron microscopy in the dilute copper alloys containing small amounts of V3Ga particles prepared by quenching from the liquid state and aging. No superconductivity could be observed at 4.2 K in as-quenched and/or in overaged samples. The highest T/sub c/ (=12.5 K), T/sub c/ (=9.6 K), and J/sub c/ (=525 A/cm2) were obtained by aging at 700 0C for 96 h and corresponded with the structure of fine V3Ga precipitates dispersed homogeneously in the copper matrix. Therefore, it is concluded that superconductivity in these alloys results from the superconducting path due to the proximity effect of the superconducting V3Ga particles
