SUPERCONDUCTIVITY OF QUENCHED CONDENSED PB-BI ALLOYS

By quenched condensation of various alloys in the Pb-Bi-system the superconducting transition temperature of an amorphous phase could be obtained for all concentrations. During annealing new unknown phases were found and their transition temperatures were measured. The dependence of Tc on electron concentration of the amorphous phase is compared with that of the α-phase solid solution. A variation of the interaction parameter V with concentration is discussed. © 1968 Springer-Verlag.
