Abstract

An advantageous device structure for the efficient electrical detection of spin Hall effect has been demonstrated by using a V-shaped ferromagnetic wire. The spin Hall voltages were evaluated by the combination between the spin absorption into the Platinum strip and the desired spin structure in the V-shaped Permalloy wire. Rectangular-shape field dependence of the spin Hall signal with bistability in the zero magnetic field reveals the validity of the developed device structure. We also showed that the domain wall chirality trapped at the corner of the V-shape wire can be determined from the sign of the spin Hall voltage.
