Effects of<i>s</i>-<i>d</i>Interaction on Transport Phenomena

Abstract

The effects of the so-called s-d interaction on transport phenomena of ferromagnetic metals and alloys are discussed. Electrical and thermal conductivities and thermoelectric effect are calculated with the simple molecular field approximation, and an anomalous thermoelectric effect is expected in these substances. In sufficiently low temperatures, the disordering of spin system is described by the collective mode of spin wave. The calculations of transport coefficient by using the spin wave approximation are also carried out.
