摘要：

A controllable spin filter is proposed by theoretically investigating spin polarization in a magnetic microstructure constructed on surface of GaAs/AlxGa1-xAs heterostructure by patterning a horizontally-magnetized ferromagnetic stripe. Due to a broken intrinsic symmetry by spin-orbit coupling, a spin polarization effect appears in the magnetic microstructure. Degree of spin polarization can be modified by changing strength of spin-orbit coupling, which may be helpful for design of controllable spin-polarized source.
