Description
Results are presented of measurements of the superconducting transition temperature T/sub c/, lattice constant a, magnetic susceptibility /sub chi/, and critical field H/sub c/2 for many Nb3Al and V3Si-based ternary phases and Nb3SnH/sub x/. For V3Si-based ternary systems and Nb3SnH/sub x/ the density of states at the Fermi level N(epsilon/sub F/) sharply decreases with the concentration of the alloying element. The variation of N(epsilon/sub F/) in these ternary systems cannot be explained by the variation of a. In ternary phases Nb3(Al/sub 1-x/dY/sub x/), where Y can be Ge, Ga, Sb, or Se, a quite clear correlation is revealed between T/sub c/ and a. The dependence of T/sub c/ on V in these systems is due to the variation of the matrix element of the electron-phonon interaction
