Quantification of current-induced torque and magnetic anisotropy. Normalized R_AHE (i.e., cosθ) as a function of H^ext for positive (along y) and negative (along −y) currents, when H^ext is (a) in the yz-plane and b in the xz-plane. Insets of (a) and b show the measurement scheme. The curves were obtained at 300 K and β = 3°. c Values of H₊^ext(θ) − H₋^ext(θ) determined from the data in (a) (squares) and best-fit curve obtained using Eq. 2 (solid line). d Values of H₊^ext(θ) + H₋^ext(θ) determined from the data in a (squares) and best-fit curve obtained using Eq. 3 (solid line). e Dependences of T^AD (black line) and H^an (blue line) on θ. f ξ^AD as a function of θ
