noncollinear antiferromagnet

All moments add up to a net magnetisation: an ordinary magnet. Spin splitting is the same in every direction (s-wave).

ordered ≤ 5.5 K (−268 °C)Colour: where that sits relative to 25 °C. Saturation: how much margin it has.

Method	For the MSG in a non-standard setting, the basis transformation used is as indicated in the paper: (3,0,0), (0,3,0), (0,0,3), so the structure can be directly compared with Fig. 9 in the publication. The transformation (2,1,0), (-1,1,0), (0,0,3); (0,0,0) to the standard setting of the MSG from the parent SG results in a unit cell 3 times smaller. The assignment of the MSG to R-3'c' in the paper was incorrect. The correct MSG is R3.1, corresponding to the magnetic structure shown in Fig. 9.

Symmetry

Stereogram of the magnetic point group: each operation applied to one direction. Filled = upper hemisphere, ring = lower; red operations include time reversal. Lines are mirrors; polygons are 2/3/4/6-fold axes; the centre ring is inversion.

Moment components are along the crystal axes a, b, c (μ_B), as magCIF writes them. Symmetry generates the rest of the cell from these sites.
