FIG. 1.

A schematic illustration of a model of FM/SC/FM structures. Electrons with the wave vector k σ  = (kx σ , ky σ , kz σ ) = ( k || σ , kz σ ) transmit through the potential barrier with height V of width d along z. The arrows show the magnetization direction in region 1 and region 3.

FIG. 2.

(a) The spin orientation corresponding to in the kx ky plane. (b) The spin orientation corresponding to in the kx ky plane.

Image of FIG. 3.
FIG. 3.

(Color) (a) The MR ratio for three different barriers, GaAs, GaSb, and GaAs, without SOI as a function of barrier thickness. (b) A schematic illustration of energy levels of electrons with spin σ(↑,↓) entering the SC barriers with cubic Dresselhaus SOI.

Image of FIG. 4.
FIG. 4.

(Color) The MR ratio for two effective masses of 0.067 me and 0.041 me as a function of spin-orbit coupling constant γ.
