_exptl_crystal_magnetic_properties_details
;
NPD
Position structure, including cell parameters, from a room temperature determination from another study.
FM on the plane ac
The moment component on the basal plane could not be determined. Here a direction on the ab plane corresponding to a maximal symmetry has been arbitrarily chosen.

_active_magnetic_irreps_details
;
1k magnetic structure
Two irreps are involved as primary. This means that from the viewpoint of Landau theory two order parameters are involved in the magnetic ordering.
