Magnetic structure with all atoms

Magnetic structure with only magnetic atoms

• NPD
• The model represented graphically in the article does not corresponds to a 2k structure with the pair of propagation vectors mentioned in the article: (1/2 0 1/2) and (0 1/2 1/2), but to the vectors (1/2 0 1/2) and (0 -1/2 1/2), which is a domain-related symmetry-equivalent pair.

• 2k magnetic structure
• k-maximal magnetic symmetry (2 possible)
• The secondary irrep mN1+ corresponds to the symmetry-allowed Fe1 mz component, which is zero in the model.
• The active primary irrep has 4 k-vectors in its star, while the model involves only two of them. Different sets of pairs can describe different or equivalent structure models depending on the pair chosen.
• A possible alternative non-equivalent 2k model with a different choices of the pair of k-vectors, and 3k or 4k models, which could equally fit the data, are not considered in the article.
• The active primary irrep for the two k vectors involved has two degrees of freedom, allowing a non-zero my component of the Fe1 moment that is zero in the proposed model.
