The inverse spin-Hall effect (ISHE), conversion of spin currents into charge currents, has recently been observed in paramagnetic metal/ferrimagnetic insulator bilayer films by means of the spin pumping. Here we investigate the ISHE induced by the spin pumping on Pt/Ti/Y3Fe5O 12 and Pt/Ti/BiY2Fe5O12 films, where the Y3Fe5O12 (BiY2Fe 5O12) and Pt layers are separated by thin Ti layer. In these systems, we measured electric voltage due to the ISHE in Pt/Ti/Y 3Fe5O12 (BiY2Fe5O 12) systems at room temperature. The experimental results show that the ISHE signal disappears in the Pt/Ti/Y3Fe5O 12 (BiY2Fe5O12) systems. These results indicate that the spin pumping between Y3Fe5O 12 (BiY2Fe5O12) and Ti layer is suppressed. This method enables us to suppress the spin currents without non-magnetic insulators.
