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 limitT≫ ¯ TK andT≪¯ TK to order (In ¯T K /T)−4 where ¯T K 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.
