Spin-dependent transport in lateral periodic magnetic modulations: a novel scheme for spin filters

Abstract

A novel scheme for spin filters is proposed by studying the coherent transport of electrons through the quantum wires with lateral magnetic modulations. Unlike other schemes in the literature, the modulation in our scheme is much weaker than the Fermi level. Large spin polarization through the filter is predicted. Further study suggests the robustness of this new spin filter.
