Resonant tunneling in magnetic semiconductor tunnel junctions with arbitrary magnetic alignments

►Double barrier FS tunnel junctions. ►Varied angle between the magnetic directions of two FS's. ►The TMR ratio linearly varies with sin2(θ/2). ►The behavior of TMR with the variation of quantum well width is periodic. ►The features of the spin-polarized resonant tunneling for the heavy and light holes are much different.
