✦ Synopsis

We theoretically investigate the transmission probability, the conductance as well as the spin polarization of the electrons in a nanostructure with the periodic magnetic-electric barriers. These observable quantities are found to be strongly affected by both the magnetic configuration and the number of the periodic magnetic-electric barriers. When the number of periods increases, the resonance splitting increases.

Using the transfer matrix method, the transmission probability, the spin polarization and the conductance of the ballistic electron are studied in detail in a nanostructure with the periodic applied bias and magnetic barriers. We find that these observable quantities sensitively depend on the number
