Proximity Induced Meissner Effect in Dirty Normal Metals

Abstract

Temperature dependences of the proximity induced Meissner diamagnetization in dirty normal metals are calculated by use of the Usadel equation. Besides the effect of the normal impurity scattering, that of the magnetic one is investigated. Especially the Kondo effect is examined based on the Anderson Hamiltonian employing a scheme that interpolates magnetic and non-magnetic behaviors, and a crossover between these two has been described.
