| 英文摘要 | Electron spin-dependent transport properties have been theoretically investigated in two-dimensional electron gas (2deg) modulated by the magnetic field generated by a pair of anti-parallel magnetization ferromagnetic metal stripes and the electrostatic potential provided by a normal metal schottky stripe. it is shown that the energy positions of the spin-polarization extremes and the width of relative spin conductance excess plateau could be significantly manipulated by the electrostatic potential strength and width, as well as its position relative to the fm stripes. these interesting features are believed useful for designing the electric voltage controlled spin filters.
