Abstract

The superconducting transition temperatures Tc and the pressure dependences of Tc have been determined as a function of x in the compounds V75-xTMxGa25 where TM is the transition metals Cr, Mn, Fe, or Co. In these systems Tc is a strongly dependent, but a universal function of the electron per atom e/a ratio. Systematic trends in the relative pressure derivatives (1/Tc)(∂Tc/∂p) have also been observed for these compounds, but the best correlation of the pressure data is with concentration x not with e/a.
