NPD
Position structure absent in the paper. The one at room temperature retrieved from another work (ICSD) is used here.
The structure is described using a F-centered setting

;
1k magnetic structure
k-maximal magnetic symmetry (3 possible)
1-dim small irrep as primary. The irrep has two k-vectors related by the 4-fold rotation. Only one is involved in the structure.
Probably a 2k magnetic non-collinear structure under the same irrep but involving its two k-vectors with the same weight could have also equally fit the data.
