  For the last years spin effects in semiconductors have been of great interest
not only in the context of solid state physics, but also for their potential
usage in technology. In this paper we give a short review of spintronic
materials, in which electron spin as an additional degree of freedom is
exploited. Afterwards, we discuss the properties of classic, non-magnetic
semiconductors, where the efforts are put on enriching the traditional
semiconductor technology engaging the electrical effects of spin effects.
Various phenomena and scientific state of the art is highlighted.
