MAGNDATA entry 0.5 · source

s-wave compensated ferrimagnet

Opposite moments cancel, but the two sublattices aren't related by any symmetry, so the bands split like a ferromagnet's (s-wave).

Spin group ¹3̄: each symmetry marked ¹ keeps every spin, ² swaps up and down.

ordered ≤ 122 K (−151 °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 (μ_B), as magCIF writes them. Symmetry generates the rest of the cell from these sites.
