Abstract

The possibility to induce polarized transmission is investigated in a system of multibarrier magnetic junction. In the undeformed system, the transmission is shown to depend on the incident energy but almost independent of inhomogeneity of potential barrier. A proper selection of incident energy is found sufficient to control both direction and strength of spin polarization. When deformation of momentum wave-vector is introduced, the spin polarization does not only change its dependence on energy but also its intensity. This provides evidence that besides energy, deformation of momentum wave vector could also influence and be used to drive spin of the transmitted current; gaining further control on both direction and intensity. A short survey on the role of local magnetic splitting, ordering of local magnetic field on the spin polarization is also given.
