Query: Nonvanishing spin Hall currents in the presence of magnetic impurities   The intrinsic spin Hall conductivity in a two dimensional electron gas with
Rashba spin-orbit coupling is evaluated by taking account of anisotropic
coupling between magnetic impurities and itinerant electrons. In our
calculation Kubo's linear response formalism is employed and the vertex
correction is considered. In the semiclassical limit $\mu \gg 1/\tau$, a
non-vanishing spin Hall conductivity $\sigma^{}_{sH}$ is found to depend on the
momentum relaxation time $\tau$, spin-orbit splitting $\Delta$ and the
anisotropic coefficient of interaction between itinerant electrons and magnetic
impurities. The clean limit of $\sigma^{}_{sH}$ is in the region of $e/8\pi
\sim e/6\pi$, depending on the anisotropic coefficient.
