NPD
Transition temperature is not specified.
Ferrimagnetic on the ac plane
The direction of the Mn1 on the basal plane cannot be determined from NPD data. A direction of maximal symmetry has been assumed (another non equivalent possible direction with maximal symmetry is along (1,1,0)).
;

_active_magnetic_irreps_details
;
1k magnetic structure
k-maximal symmetry
Two irreps as primary: two order parameters in the sense of Landau theory are involved.
One irrep corresponds to the spin mode along c, and the other one to the Mn1 moment component on the ab plane.
