Electron coherent tunneling in low-dimensional magnetic quantum structures

We study electron coherent tunneling properties through the magnetic-barrier structure. The characteristics of wave-vector filtering, resonance splitting, and electric field effects have been investigated. The results indicate that the features of transmission resonance in the magnetic-barrier structure not only depend on the structure and the incident wave vector, but also strongly depend on the electric field. There exist rich and interesting features for electrons tunneling through the magnetic-barrier structure which is arranged with nonidentical magnetic barriers and wells.
