Colloquium20150407-Spin Hall Effect

Abstract: Spin Hall effect (SHE) refers to the generation of transverse spin current in nonmagnetic solids by an applied electric field due to relativistic spin-orbit coupling. Spin current generation, detection and manipulation are three key elements of the emerging spintronics. Large room temperature SHE not only provides dissipationless spin current but also is used to… Read more »
