To clearly understand the magnetization switching in the GdFeCo/Pt Hall bar structure, we investigated the magnetization switching phenomena via electric and optical techniques, such as the anomalous Hall measurement and simultaneously the magneto-optical Kerr effect imaging. It is found that the SOT-induced switching is accomplished via the local nucleation of domains and domain wall motions. It is also observed that the anomalous Hall signal due to spin-orbit torque was slightly smaller compared to that of the magnetic field-induced reversal. We confirm that the smaller signal is due to the incomplete magnetization switching in the Hall bar.
