MAGNDATA entry 0.835 · 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 ≤ 89 K (−184 °C)Colour: where that sits relative to 25 °C. Saturation: how much margin it has.

Largest moment component	5.4 μ_B
Method	Neutron powder diffraction. Ferrimagnetic structure: parallel moments at Dy atoms at 2a, 4g2 positions and antiparallel at 4g1 position. At higher investigated temperatures (40, 65, 80 K) magnetic moments at 4g1 are not detectable and structure is ferromagnetic.

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.
