TRANSPORT PROPERTIES OF DILUTE MAGNETIC ALLOYS

The electrical resistivity, thermopower, and the electronic part of the thermal resistivity of dilute magnetic alloys are calculated in the framework of the Suhl-Nagoaka theory. Using Bloomfield's and Hamann's solution of the Nagaoka equations, we derive expressions for the transport quantities in the limit T≫ - TK and T≪- TK to order (In -TK/T)-4 where -TK is the Kondo temperature which may depend on the spin independent scattering. We find that the thermopower and deviations from the Wiedemann-Franz law in this limit decrease as |In -TK/T|-3 if one neglects a trivial temperature dependence of the thermopower due to the electron-phonon interaction. © 1969 Springer-Verlag.
