Effect of a Magnetic Impurity on the Conductivity in the Weakly Localized Regime

Abstract

The effect of a magnetic impurity on the life time of the conduction electrons and on the conductivity in the weakly localized regime are investigated by the perturbational method in terms of exchange coupling constant J. It is shown that the corrections for those quantities are proportional to J³λ^d−1T^d⁄2−2(1+2ρ₀J ln ε_F⁄T)⁻³ within the framework of the most divergent approximation, where d is the dimensionality and λ the degree of disorder.
