Estimation of spin-orbit torques in the presence of current-induced magnon creation and annihilation

This paper demonstrates that current-induced magnon creation and annihilation significantly distort spin-orbit torque estimates in various bilayer systems, leading to substantial overestimations if unaccounted for, and proposes a reliable method to quantify and correct these effects by combining nonlinear magnetoresistance measurements.
