The inverse spin-Hall effect, conversion of spin currents into electric voltage, has been investigated in Ni81Fe19/Pt bilayer films with different length and width. We measured the electric voltage generated by the inverse spin-Hall effect induced by the spin pumping at room temperature. The experimental results indicate that the electric voltage induced by the inverse spin-Hall effect is proportional to the length of Ni 81Fe19/Pt bilayer films. In contrast, the electric voltage exhibits almost no variation by changing the width of the Ni 81Fe19/Pt films. These results are consistent with the inverse spin-Hall effect model.
