Correction of out-of-plane spin torque extracted from second harmonic Hall measurements: Role of antisymmetric planar Hall effects
The authors identify here a previously overlooked artifact in second harmonic Hall measurements: the antisymmetric planar Hall effect (APHE). Using rutile RuO${}_{2}$ as a model system, they show that APHE mixes with the cos(2\ensuremath{\varphi}) term and leads to up to 20% overestimation of the out-of-plane damping-like torque. A corrected analytical model is presented to accurately evaluate $z$-spin torque components in low-symmetry spin--orbit materials.
