Magnetic structure with all atoms

Magnetic structure with only magnetic atoms

• NPD and NSD
• Positional structure is not provided. Here one for a similar composition at 2K retrieved from the ICSD has been used.
• Transition temperature is not reported. For a similar composition T_N=50K has been reported (same reference as the ICSD structure) and this information is included here.
• The Fe magnetic moment is significantly smaller than the one reported in other studies (see #1.434)
• The relative sign of the moment of the Fe site with 0.05 occupancy, with respect to those in the layers, is undefined in the reference. Here a sign has been assumed, which makes it to be FM coupled with the closest Fe site in the layer.

• 1k magnetic structure
• k-maximal magnetic symmetry (4 possible)
• 2-dim small irrep along a special direction as primary
• The star of the active irrep has two k-vectors.
• The positional structure has a monoclinic distortion (space group P2_1/m). This structural distortion has been reported to take place simultaneously with the magnetic ordering, and it is consistent with the effective space group of the positional structure resulting from the MSG. It therefore fulfills the symmetry conditions for being a magnetic induced structural effect.
