Electronic Transport in Nanostructures Consisting of Magnetic—Electric Barriers

We present a theoretical investigation on the transport properties of the nanostructures consisting of magneticelectric 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.
