Examination of Current-Induced Magnetic Field in the Slab Geometry: Possible Origin of Spin Hall Effect

We estimate the strength of current-induced magnetic field (CIMF) in the two-dimensional slab geometry for Spin Hall Effect (SHE) observed recently by Kato et al. and Wunderlich et al. and show that if the factor gm^*/m, where g is the Lande factor and m^* and m are effective and pure masses, respectively, is equal to the numerical value at the surface of the semiconductor, then the CIMF can describe the SHE.
