Extended Data Fig. 5: Angular dependence of linewidth modification and free energy.
From: Signatures of magnetism control by flow of angular momentum

a, φH-dependence of the calculated modulation of linewidth d(ΔH)/dI. b, φH-dependence of free energy F. Around the HA (shaded areas), the energy barrier vanishes and all the static torques acting on M cancel. In this case, the magnetization has a larger precessional cone angle, leading to an enhanced d(ΔH)/dI values.
