Since the charge transport has a sensitive property near the boundary, the GH shift and spin polarization are reexamined with a parallel double barrier magnetic nanostructure. It shows there exists a much stronger GH shift and spin polarization when the transmitted wave vector is much closer to zero by modulating the magnetic fields strength and incident energy. Furthermore, the influence on spin polarization is studied by changing the angle between two magnetic fields. It revealed that a stable spin polarization can be obtained by changing angle under some specific applied voltage and incident energies. Our results indicate a need for caution in boundary condition and tuning of angle. These interesting properties may provide good ideas to design and fabricate a spin beam splitters or filters.
