Ballistic electron transport in a magnetic nanostructure periodically modulated by the δ-dopingδ-doping

In this paper, we theoretically investigate the electron transport in a magnetic nanostructure modulated by the periodic δ-dopingδ-doping. From our numerical results, it is found that the electron transport is strongly dependent on the number m of periods. For m  >1>1, the spin splitting occurs in each resonant domain, and the number of the spin-splitting peaks in each resonant domain is m−1.
