摘要：

Inverse spin-Hall effect (ISHE) was investigated in Ni81Fe19/Pt and Ni81Fe19/Cu films. By applying a microwave and a magnetic field to the films, a spin current is injected into the paramagnetic layer from the ferromagnetic Ni81Fe19 layer due to the spin-pumping effect operated by the ferromagnetic resonance. In the Ni81Fe19/Pt film, this spin-current injection gives rise to electromotive force, which is attributed to ISHE in the Pt layer. In the Ni81Fe19/Cu film, in contrast, this electromotive force disappears, indicating an important role of strong spin-orbit interaction in ISHE. (C) 2008 American Institute of Physics.
