Position structure from a determination at 293K
It is mentioned that an alternative model with the spins along a fits equally well the data.

1k magnetic structure
k-maximal magnetic symmetry
1-dim irrep as primary
Weak FM is mentioned as observed, and it is speculated as an additional FM spin canting. However the symmetry of the structure is incompatible with a secondary induced FM effect.
