Transport Properties of Transition-Metal Impurities in a Superconductor: Magnetic Case

Abstract

A theory of transport properties of superconductors containing magnetic impurities is developed. Calculations are based on the Anderson model in the magnetic case and the Hartree-Fock approximation is employed. The temperature-dependence of the thermal conductivity, the ultrasonic attenuation and the nuclear-spin lattice relaxation time are investigated. The electromagnetic absorption at T=0 is also calculated. The experimental data of these quantities on alloys Zn-Mn and Pb-Mn are analyzed.
