Spin-dependent quantum transport in periodic magnetic modulations: Aharonov-Bohm ring structure as a spin filter
arXiv:cond-mat/0403290 · doi:10.1063/1.1779352
Abstract
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 the ring structure. Large spin polarized current can be obtained with many energy channels.
