Comments:

NPD
Non-standard setting Pbnm of parent
Above 228K (up to 720K) a spin reorientation transition takes place (see #0.757)
The structure model includes small deviations of the O sites from stoichiometric occupancies (with the O2 occupancy larger than 1), which are not included here.

Comments (symmetry):

1k magnetic structure
k-maximal magnetic symmetry
1-dim irrep
