Magnetism and Transport Phenomena in bcc Iron

Magnetic susceptibilities and electronic specific heat are calculated for bcc iron in the band model by making use of the calculated density of states by Connolly. From the observed temperature variation of the magnetization, the dependence on the magnetization of exchange energy is estimated. Electrical resistance, thermal conductivity and thermoelectric power are also calculated for paramagnetic bcc iron in a simple model of Fermi surfaces by averaging electron-phonon interactions over Fermi surfaces. It is shown that the observed temperature variations of susceptibility, electrical resistance and thermoelectric power in the paramagnetic state and of specific heat can be explained by our calculated results in the simple band model.
