Spin Seebeck Effect in Ni$_{81}$Fe$_{19}$/Pt Thin Films With Different Widths |
| |
Abstract: | The spin Seebeck effect (SSE) has been measured in Ni $_{81}$Fe $_{19}$ thin films which have different widths by using the inverse spin Hall effect (ISHE) in a Pt wire. The ISHE voltage induced by SSE is enhanced by lengthening the Pt wire. Combined with ISHE, SSE is applicable to the production of electric generators in which the thermoelectric figures of merit are tunable in terms of device structure. |
