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