Magnetic structure with all atoms

Magnetic structure with only magnetic atoms

• NPD
• Refined model for data at 1.5K and a magnetic field of 8T applied on the powder sample. See #3.22 and #3.23 for the structures reported at zero field and at 5T.
• The structure is reported in the article in a non-standard setting of the MSG, with a shift -1/4 of the origin along a. This origin shift is not mentioned in the article, and it is maintained here.

• 2k magnetic structure
• 6-dim 3k full irrep along a special direction restricted to only one of the three k-vectors in the star as primary irrep
• 3-dim k=0 irrep as primary irrep corresponding to the FM component
• The MSG allows a third irrep mGM5+ (AFM). This third irrep is present in the spin arrangement with a weight exactly of the same magnitude as that of mGM4+(FM) such that they yield the total moment of the atom Eu1_1 in the asymmetric unit, while together they nullify any contribution to the moments of the other four atoms, whose arrangement is only described by the irrep mX5-.
• The relative sign of the amplitudes of the mGM4+ and mGM5+ components in the spin arrangement with respect to that of the mX5- component is arbitrary, as they correspond to domain-equivalent configurations. This makes the relative sign of the moment of Eu1_1 irrelevant, both values yielding equivalent domains.
