Spin lattice of Sr2Er1Ru1O6Spin lattice of Sr2Er1Ru1O6

Sr2Er1Ru1O6

MAGNDATA entry 0.1008 · source
altermagnet
No net magnetisation, yet the electron bands are spin-split: the up and down spin sublattices are related only by a rotation or mirror, never by a shift or inversion.
Spin group ²2/²m: each symmetry marked ¹ keeps every spin, ² swaps up and down.
ordered ≤ 50 K (−223 °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.
