The charge and the spin of the electron are intrinsically related in its quantum behaviour, but charge and spin have been used separately for a long time.
Classical electronics displaces electrons by only acting on their charge. Magnetic information recording uses the macroscopic expression of spin, the magnetisation of the magnetic material, for storing information.
Under the impetus of several recent discoveries, a novel electronics is emerging that associates the control of spin currents and charges in novel devices. This spin electronics is promising, with low dissipation and high rates, as well as with complete integration of the "memory", "transmission" and "calculation" functions for higher performance of nanoelectronic circuits.
In the longer term, the magnetism/optics connection due to spin-orbit interaction, and the low coupling of spin with its surroundings, promise spin-offs in the fields of optoelectronics and quantum information, with hybrid devices that will associate metals, oxides, semiconductors and molecules.The Spintronics axis conducts research work at an early stage of these themes, with an excellent world standard.
