Extended Data Fig. 8: Spin orientations.

a–c, Red arrows show the \([\bar{1}\bar{1}20]\)- projected spin orientations assuming that they have the tilt angle θ₀ to the (0001) plane and perpendicular to the \([\bar{1}\bar{1}20]\) (a), \([\bar{1}2\bar{1}0]\) (b) and \([2\bar{1}\bar{1}0]\) (c) directions. The orientation parameters used in equation (7) become sinτ = 1. In a, η = θ₀; in b and c, \(\sin \,\tau =\sqrt{{\sin }^{2}{\theta }_{0}+\frac{1}{4}{\cos }^{2}{\theta }_{0}}\) and η = arctan(2tanθ₀). In the present \([\bar{1}\bar{1}20]\) projection, b and c cannot be distinguished.
