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

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 J 3 λ d -1 T d /2-2 (1+2ρ 0 J ln ε F / T ) -3 within the framework of the most divergent approximation, where d is the dimensionality and λ the degree of disorder.
