Abstract
With the help of the transfer matrix method, the transmission probability, the electron conductance and the spin-polarization of the ballistic electron are in detail studied in a nanostructure with the periodic bias. It is shown that these observable quantities strongly depend on the number of the periodic bias. With the number of the periods increasing, the resonance splitting increases, so the number of the resonance peaks is increasing and the peaks become sharper as well as the spin-polarization being enhanced, although the average magnetic field of the structure is zero.
