Behaviors of a Magnetic Impurity at Low Temperatures of Weakly Localized Regime

Abstract

The interplay between the Anderson localization and the Kondo effect in the low temperature region of the weakly localized regime is investigated on the basis of the Anderson Hamiltonian. By the perturbational expansion in terms of the Coulomb integral between d-electrons, it is shown that the quantum corrections to the conductivity have the ln T-dependence for the two-dimensional systems and \sqrtT-dependence for the three-dimensional systems, and that the magnetic susceptibility behaves anomalously even at low temperatures.
