Giant magnetoresistance in a two-dimensional electron gas modulated by ferromagnetic and Schottky metal stripes

In this paper, by using the transfer matrix method, we theoretically investigate the magnetoresistance (MR) effect in a magnetic-electric barrier nanostructure. The detailed numerical results show that a considerable MR effect can be achieved in such a device and the MR ratio strongly depends on the magnetic-electric barrier height and the distance between the ferromagnetic and Schottky metal stripes.
