MAGNDATA entry 0.1163 · source
s-wave ferrimagnet
Opposite moments of different size leave a net magnetisation.
Spin group ¹m¹m¹m: each symmetry marked ¹ keeps every spin, ² swaps up and down.
ordered ≤ 527 K (254 °C)Colour: where that sits relative to 25 °C. Saturation: how much margin it has.

MethodNPD. Nuclear and magnetic Rietveld refinements were carried out using FullProf; representation analysis used SARAh and k-search within FullProf.

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.
