 Title: Spin Hall Drag Author: Badalyan, S. M.; Vignale, Giovanni, 1957- Keywords: nanoscale physics mesoscale physics Date: 2009-07 Publisher: arXiv Citation: arXiv:0907.2995v1 Abstract: We predict a new effect in electronic bilayers: the {\it Spin Hall Drag}. The effect consists in the generation of spin accumulation across one layer by an electric current along the other layer. It arises from the combined action of spin-orbit and Coulomb interactions. Our theoretical analysis, based on the Boltzmann equation formalism, identifies two main contributions to the spin Hall drag resistivity: the side-jump contribution, which dominates at low temperature, going as $T^2$, and the skew-scattering contribution, which is proportional to $T^3$. The induced spin accumulation is large enough to be detected in optical rotation experiments. URI: http://hdl.handle.net/10355/7658
