Charge and spin transport in artificial magnetic structures, like nanopillar spin valves, planar tunnel junctions, and mesoscopic double barrier junctions (single electron transistors) are briefly surveyed, with particular emphasis on magnetoresistance effects and current induced magnetic switching and spin dynamics. The methods of spin current generation are also discussed, particularly the method based on spin Hall effect.
