  We start closing a gap in the comparison of experimental and theoretical data
associated with the spin Hall effect. Based on a first-principles
characterization of electronic structure and a semiclassical description of
electron transport, we compute the skew-scattering contribution to the
transverse spin and charge currents generated by spin and anomalous Hall effect
in a Co/Cu multilayer system doped with Bi impurities. The fact that the
created currents cross the interface between the two materials strongly
influences the efficiency of charge to spin current conversion, as demonstrated
by our results.
