摘要：
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. owing 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 the spin-orbit coupling parameter in nonmagnetic metals via the nonlocal spin-injection technique. (c) 2006 Elsevier B.V. All rights reserved.
