Anisotropic phase boundary in RuCl3. a The magnetotropic coefficient k of RuCl3 at T = 1.3 K and B = 17.5 T as magnetic field is rotated from the honeycomb planes (θ = 90°) to the perpendicular orientation. Entry into the long-range antiferromagnetically ordered state (gray region) is marked by a sharp jump down in the magnetotropic coefficient (vertical blue line). b Field orientation scans at various fixed magnetic fields (similar to a) allow a complete mapping of the antiferromagnetic phase boundary
