MAGNDATA entry 0.1130 · source
antiferromagnet
No net magnetisation, and up and down sublattices are related by a shift or by inversion, so the bands stay spin-degenerate: a conventional antiferromagnet.
Spin group ¹3̄ × ²1: each symmetry marked ¹ keeps every spin, ² swaps up and down.
ordered ≤ 96.2 K (−177 °C)Colour: where that sits relative to 25 °C. Saturation: how much margin it has.

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 (μB), as magCIF writes them. Symmetry generates the rest of the cell from these sites.
