  Spin Hall effect in a nonlocal spin-injection device is theoretically
studied. Using a nonlocal spin-injection technique, a pure spin current is
created in a nonmagnetic metal (N). The spin current flowing in N is deflected
by spin-orbit scattering to induce the Hall current in the transverse direction
and accumulate charge at the edges of N, yielding the spin-current induced Hall
effect. We propose a method for extracting information for spin-orbit
scattering in nonmagnetic metals.
