Local injection of pure spin current generates electric current vortices

Prof. Ya. B. Bazaliy, University of South Carolina, Department of Physics and Astronomy, Columbia, SC, USA;

Electrons carry charge and spin, and thus their motion may induce both electric and spin currents. The former is familiar to all, while the latter is more exotic. We will discuss generation and manifestations of spin current, its interplay with electric currents, and then focus on a specific effect where pure spin current generates electric currents in a device that is not connected to any outside source or sink of charge. We further discuss how the generation of such electric currents enhances spin diffusion.
