Electronic Transport in Nanostructures Consisting of Magnetic-Electric Barriers
-
Abstract
We present a theoretical investigation on the transport properties of the nanostructures consisting of magnetic-electric barriers produced by the deposition, on the top of a heterostructure, of metallic ferromagnetic stripe with an applied voltage. Both the transmission probability and the conductance are found to be greatly dependent upon the applied voltage. When a positive voltage is applied to the stripe, both the transmission probability and the conductance shift towards low-energy region and increase. Conversely, they move towards high-energy direction and reduce for an applied negative voltage.
