Abstract

The resonance splitting and wave-vector filtering for electron tunneling through magnetic superlattices are investigated theoretically. Two kinds of magnetic superlattices are examined. One is a periodic arrangement of identical magnetic barriers while the other is periodically juxtaposed with two different magnetic barriers. In general, one resonant domain in the former splits into two resonant domains in the latter. It is confirmed that both the resonance splitting and wave-vector filtering strongly depend on the structure of the magnetic superlattices. The numerical results indicate that the magnetic superlattice, which is a periodic arrangement of two different magnetic barriers, possesses stronger wave-vector filtering.
