Quantum interference in Aharonov-Bohm (AB) ring structure provides additional control of spin at mesoscopic scale. We propose a scheme for spin filter by studying the coherent transport through the AB structure with lateral magnetic modulation on both arms of ring structure. Large spin polarized current can be obtained with many energy channels. (C) 2004 American Institute of Physics.
