NSD
Position structure from a determination at room temperature
Co moment: 4.2
Apparently the model is not the result of a systematic least-squares fit of the data
See #0.193 and #0.383 for a different model of this structure with higher symmetry and a single irrep involved.
See #0.385 for a model with rather different symmetry also involving two irreps.

_active_magnetic_irreps_details
;
1k magnetic structure
Two irreps as primary: two order parameters are involved in the sense of Landau theory, one of them being very small.
From ME properties the authors propose that the magnetic point group of the system should be 2'_x. 
The reported magnetic structure has however as magnetic point group 2'_x/m_x. Assumedly the system has in addition a weak FM component along b, which would reduce the point group to 2'_x.
