Abstract
In order to consider the effect of electron-electron (e-e) interactions on the quantum transport in magnetic multilayers, the spinor Boltzmann equation and Poisson equation are jointly investigated. The analytical expressions of the spinor distribution function and the self-consistent average potential associated with e-e interactions are obtained, and the dielectric function in the self-consistent average potential is naturally generalized. Then we apply these results to the system of ferromagnet/insulator/dilute-magnetic-semiconductor (FM/I/DMS) layers, and study the time and position dependences of the charge current, spin current and spin accumulation in the FM/I/DMS system.
