Magnetic Barriers

In this paper, we study the electron transport properties in the double non-collinear δ-magnetic barriers within 2-dimensional electron gas. We find that the transmission of spin current depends on the relative orientation of each magnetic barrier. In addition to the well-known unpolarized configurations in an antiparallel magnetic barrier structure, we also find that there exists infinite unpolarized structures due to the time-reversal symmetry. These structures will be important in the designs of spin valve.
