WebThe physical mechanism of the spin Hall effect is in the dependence of the direction of electron scattering on an unpolarized target from the spin direction due to spin-orbit interaction. There are two types of this effect: internal and external. WebAug 5, 2013 · The inverse spin Hall effect (ISHE) has been observed only in nonmagnetic metals, such as Pt and Au, with a strong spin-orbit coupling. We report the observation of ISHE in a ferromagnetic permalloy (Py) on ferromagnetic insulator yttrium iron garnet (YIG).
