The inverse spin-Hall effect (ISHE) has been investigated using the spin pumping, spin current generation from magnetization dynamics, in Ni 81Fe19/N (N = Nb and Nb40Ti60) bilayer films. We found an electromotive force due to ISHE in Ni 81Fe19/N (N=Nb and Nb40Ti60) bilayer films. The experimental results show that the ISHE signal in the Ni 81Fe19/Nb40Ti60 bilayer film is greater than that in the Ni81Fe19/Nb bilayer film, suggesting an important role of the impurity doping for ISHE and the spin pumping in Nb.
