Spintronics is often defined as a new type of electronics harnessing not only the charge of the electron but also its spin. Its development was kicked off in 1988 by the discovery of the Giant Magnetoresistance of the magnetic multilayers, a phenomenon that we currently use to read the hard disc of our computer. Nowadays spintronics has become a broad field of research expanding in many promising directions.
After an introduction on the fundamentals of spintronics, I will review the developments of today and the perspective of applications. I will mainly focus on three topics: 1) Microwave generation by spin transfer, a field of research with fast recent advances anticipating applications shortly in telecommunications. 2) Spintronics with graphene and carbon nanotubes, an extremely promising direction to extend the limits of electronics with semiconductors (the “beyond CMOS” perspective). 3) Oxitronics: I will present works on devices based on magnetic, ferroelectric and multiferroic oxides and describe applications like ferroelectric memories and neuromimetic components.
