Correlations between the Transition Temperature ofNb3Ge and the Normal-State Resistivity

Abstract

Correlations of $T_c$ with features of the normal-state resistance as a function of temperature for ${\mathrm{Nb}}_3$Ge films are discussed. It is found that high-$T_c$ samples have smaller normal-state residual resistivities than low-$T_c$ samples and, secondly, that $\frac{d\rho }{\mathrm{dT}}$ at high temperatures is smaller for low-$T_c$ samples.
