Relaxation processes due to collisions involving conduction electrons and magnon solitons in magnetic semiconductors

Abstract

The statistics of collisions of conduction electrons with magnon solitons in a ferromagnetic semiconductor with an easy axis of anisotropy is considered by taking into account the exchange interaction of the Vonsovsky type. The relaxation time of such collisions is calculated in the framework of the nonequilibrium-statistical-operator technique. Possible manifestations of the discussed mechanism in scattering experiments are discussed. © 1991 The American Physical Society.
