NPD
Mn1 moments remain disordered
Same Mn2 spin arrangement as in Sr2Mn3Sb2O2 (see #2.27)
see also (Nath et al., Phys. Rev. 81, 224513 (2010))
;

_active_magnetic_irreps_details
;
1k magnetic structure
k-maximal magnetic symmetry (6 possible)
1-dim irrep active
The zero value of Mn1 moments is symmetry forced.
If insulator, linear magnetoelectricity is to be expected.
