Description
A modified solid-state precipitation process for the formation of stoichiometric A-15 V3Ga is presented which results in high values of T/sub c/=15.0 K and H/sub c2/(4.2)=22 T, excellent phase homogeneity, and a high critical current J/sub c/(4.2 K)=3 x 105--6 x 104 A/cm2 over the field range 0--18 T. We find that grain boundary pinning is dominant, producing a very high specific pinning force Q/sup max/=6.4 x 104 dyn/cm2. The nonparamagnetically limited H/sub c2/ is needed to explain our high flux-pinning results
