See also Park et al., Nature Communications (2023) 14:8346 (DOI:10.1038/s41467-023-43853-4) for a similar structure, but lacking quantitative information.

Comments (symmetry):

3k magnetic structure
two primary irreps along a special direction (specific combination of the three k-vector modulations)
FM along z is symmetry allowed (secondary irrep mGM2)
