Spin Hall current and two-dimensional magnetic monopole in a Corbino disk

Published 2005-01-13Version 1

A spin Hall current can circulate in a Corbino disk with spin-orbit interactions in the presence of a radial charge current, without encountering the sample edge problem. We have suggested several experiments to directly detect and manipulate the spin Hall current in this system. A fictitious two-dimensional magnetic monopole can be created in a Corbino disk with the Rashba interaction by a circular charge current induced either by a spin Hall current in the presence of a ferromagnetic junction or by a perpendicular external magnetic field.
