Estimation of damping-like torque and field-like torque. (a) Gate voltage dependence of the relationship between the inverse of the Py thickness tPy and the spin-torque efficiency, η. The inset shows the Py thickness dependence of the saturation magnetization, μ0MS. Frequency and gate voltage dependences of (b) damping-like torque, ξDL, and (c) field-like torque, ξFL. The black and the red closed circles in all figures are the results at gate voltages of 0 and 1 V, respectively.
