MAGNDATA entry 1.662 · source

noncollinear antiferromagnet

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

ordered ≤ 74 K (−199 °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.
