This dissertation focuses on spin based phenomena of transport in low-dimensional mesoscopic systems. The work contains the theoretical discussion of an experimentally verified spin-transistor concept, which is based on controlling adiabaticity of spin evolution in dilute magnetic semiconductors. Furthermore the effect of spin dephasing on the weak localization and the weak antilocalization conductance corrections is investigated. In this context, the influence of spin-orbit interaction that scales cubically with the momentum on n- and p-type charge transport is examined. The analyses presented here are based on numerical transport simulations and semiclassical frameworks.
