The spin-dependent electron transport is theoretically investigated in a two-dimensional electron gas, which is periodically modulated by ferromagnetic and Schottky metal (SM) stripes. We find that the spin-dependent transmission and conductance as well as polarization strongly depend on the number of periods. We also find that the transmission and the polarization of transmitted beams periodically change with increasing the width of the SM stripe.

Electric Barrier

We theoretically present the spin-dependent electron transport in a two-dimensional electron gas (2DEG) with finite width modulated by magnetic–electric barriers. It is found that the transmission probability and the spin polarization are strongly dependent on the height of the electric barrier, the energy of the incident electron, the distance between the two magnetic fields, and the width of the 2DEG. These may be useful for making the practical devices.
