Temperature dependence of electrical resistivity of vanadium, platinum, and copper

Abstract

The electrical resistivities of V, Pt, and Cu (resistance ratios of 387, 7192, and 2047, respectively) were measured in the temperature range 6-327 K, and were analyzed following the theories of Bloch-Gr\"uneisen and Wilson. An excellent fit to the data was obtained over the entire temperature range. The low-temperature (6-12 K) data were analyzed for the existence of a quadratic temperature dependence; the V and Pt exhibited quadratic temperature dependences with coefficients of 370 and 110 f\ensuremath{\Omega} m ${\mathrm{K}}^{\ensuremath{-}2}$, respectively. The data did not support the use of a quadratic term over the entire temperature range.
