(a) Ground-state phase diagram of the iQC as functions of J2/J1 (J1 < 0), the canting angle θ and the ligand-valence ratio α. The contour plot of the topological charge n is also shown. (b) Magnetic textures corresponding to the symbols in panel (a). (c) Antihedgehog state for θ = 0°. (d) Antiwhirling state for θ = 70°. (e) Whirling state for θ = 90°. (f) The magnetic moments in the Tb12 clusters at the origin and at the vertices of the icosadodecahedron, shown for θ = 80°. Yellow and brown lines connect vertices on the front and back of the icosadodecahedron, respectively. (g) Long-range hedgehog order in the iQC for θ = 0°. Tb12 clusters at the origin and at the vertices of the icosadodecahedron are shown. Adapted from Watanabe (2021aView full citation).
