Schematic setup for measuring the inverse spin Hall effect (ISHE) in NiFe layer induced by longitudinal spin Seebeck. Here, ΔT and M denote the temperature gradient and magnetization directions of ferromagnets, respectively. An exchange bias field is induced in NiFe. The orientations of spin current which is emitted by the longitudinal spin Seebeck are parallel and perpendicular to the magnetization direction of the NiFe layer in panels (a) and (b), respectively.
