MAGNDATA entry 0.1191 · source

noncoplanar ferrimagnet

Opposite moments of different size leave a net magnetisation.

ordered ≤ 77 K (−196 °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.
