Thermodynamics of electrons in disordered conductors with Kondo impurities
Aronov A. G. , Zyuzin A. Yu.
The thermodynamic properties of localized spins in disordered conductors are analyzed. The magnetic susceptibility has orbital components which do not contain small terms of order (pFl /Щ~х < 1. Nontrivial contributions to the heat capacity arise in only third order in the coupling constant, in contrast with the situation in the ordinary Kondo problem.
