Temperature dependence of the resistivity due to localized spin fluctuations

Abstract

The resistivity of a dilute alloy due to localized spin fluctuations (LSF) occurring on the impurity orbitals is given by a universal function of the temperature. The resistivity is finite at T=0, then decreases with temperature as T2, T, lnT and T-1 successively. The T2 and T behaviour are in good agreement with the experimental data on AIMn. The T2 and lnT laws are expected by comparison between LSF and the Kondo effect.
