A quasi-classical, linear kinetic theory for a ferrimagnetic medium-linear magnetization

A self-consistent, quasi-classical, linear kinetic theory adopting a six-dimensional angular momentum/configuration phase space is used to develop the linear magnetization for a finite, anisotropic, magnetic medium biased with a large, uniform magnetostatic field. Only the classical dipole and quantum mechanical exchange interactions are incorporated into the theory. With suitable approximations, the equilibrium and linear magnetizations agree with existing theories. The ferrimagnetic medium is composed of two interpenetrating magnetic ion sublattices. Transverse wave oscillations result in the medium due to exchange interaction. With exchange interaction, Maxwell's equations are of differential/integral form.<>
