Spin dependent current in a modified Aharonov–Bohm interferometer

We study the spin dependent electronic transport through an Aharonov–Bohm (AB) interferometer containing magnetic quantum structures (MQSs). The transmission probability as functions of electron energy and magnetic flux through the ring shows the characteristic oscillations which are consisted of both transmission resonances and Fano resonances. The spin dependence of the transport is originated from the Zeeman term associated with MQSs and is quite distinctive in our modified interferometer.
