MAGNDATA entry 1.768 · source

p-wave magnet

Coplanar spins, no net moment, and a translation that reverses every spin: spin splitting that is odd in momentum (p-wave).

ordered ≤ 5 K (−268 °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.
