Results (IMAGE) Tohoku University Caption Experimental result of the resistance versus applied current density under the perpendicular field of -15 mT (a), and +15 mT (b). The fact that the switching direction depends on the sign of the perpendicular field indicates that the spin-orbit torque drives the magnetization reversal.
