I will review recent developments in spintronics and discuss the perspective. This first includes a presentation of the spin transfer phenomena, that is a review of results on magnetic switching and generation of microwave oscillations by transfer of spin angular momentum from an electrical current to a ferromagnetic body. The synchronization and phase locking of a collection of STO’s (Spin Transfer Oscillators) is an example of important new problem raised by the advances in the generation of microwave oscillations by spin transfer. The review will continue with results on magnetic tunnel junctions, spin transport through a semiconductor between spin-polarized source and drain, spintronics with molecules…. Finally, the natural evolution of spintronics towards nanospintronics will be illustrated by recent results on single-electron spintronics.
