Harmonic Hall measurements were performed in Pt/GdFeCo bilayers to quantify the effective field resulting from the spin-orbit torque at various temperatures, both above and below the magnetization compensation temperature (T-M). We found that the damping-like torque rapidly increased near the T-M of the GdFeCo, which was attributed to a reduction in the net magnetic moment. Moreover, most importantly, the resulting spin Hall efficiency turned out to be constant across the temperature range. Published by AIP Publishing.
