1k magnetic structure
k-maximal magnetic symmetry
1-dim small irrep
The active irrep has 3 k-vectors. Multi-k arrangements that could also fit the available data were not considered.
Only an approximate value 1.4-1.5 muB is reported for the Cr moments, and the deviations from 120 degrees of the reported relative angles are within their standard deviations. Without a precise value of the moment modulus these deviations cannot be translated in the format used here, and they have been neglected.
