Moment moduli: 3.85(11) for Co1 and 4.68(9) for Co2
Magnetic structures, similar but with different moments, are reported in the same reference for T=4K and 20K

1k magnetic structure
k-maximal magnetic symmetry (8 possible)
1-dim irrep active
A model of lower symmetry with more than one irrep active was proposed in (Santoro et al., J. Phys. Chem. Solids 27, 655 (1964)). This alternative model according to this reference can be discarded.
