Using the transfer matrix method, the transmission probability, the spin polarization and the conductance of the ballistic electron are studied in detail in a nanostructure with the periodic applied bias and magnetic barriers. We find that these observable quantities sensitively depend on the number
We theoretically study the spin-dependent electron transport in a two-dimensional electron gas modulated by ferromagnetic and Schottky metal stripes. The numerical results show that the large spin polarization can be achieved in such a device, and it is obviously dependent on the width of the Schott
