Superconducting spintronics is one of the most attractive subjects of spintronics. This article reviews superconducting spintronics based on the superconducting junctions with ferromagnetic semiconducting contact. The authors summarize recent theoretical developments with an emphasis on the interplay between ferromagnetic semiconductor (FS) and superconductor (SC). It is found that the spin-polarized transport in the superconducting junctions exhibits a rich dependence on hole types of FS, mismatches in the effective mass and Fermi velocity of holes between the FS and SC, as well as strengths of potential scattering at the interface. These systems have great intrinsic scientific importance and potential device applications including signal processing and general purpose computing.
