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.

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.

site	element	y	z	m_a	m_b	m_c	\|m\| (μ_B)
Ce1	Ce	0.1013	0.25	0	−0.1	0	0.1

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.
