Abstract

A Boltzmann equation appropriate for magnetic conductors is presented. The new element in this equation that distinguishes it from the normal case is the contribution from the spatial polarization of the electron wave functions introduced by the spin-orbit coupling. From this Boltzmann equation the wave number and frequency-dependent conductivity σ(q, ω) is calculated for the two limiting cases where the relaxation time is infinite: (a) q=0 in the presence of a uniform magnetic induction B, and (b) B=0 but q is nonzero. Case (a) is relevant to understanding magneto-optic effects, and case (b) is relevant to understanding the surface impedance in the extreme anomalous skin region (EASR).
