We report that this method suffers from various thermoelectric artifacts that have not been considered. We propose and experimentally demonstrate how to eliminate major thermoelectric artifacts using, namely, the four-direction (4-D) methods interchanging current and field polarities, which allow us to determine the magnitudes and angular dependences of spin-orbit torques more accurately than a conventional method. The proposed 4-D method will be useful for searching suitable materials for device applications operated by spin-orbit torques.
