Comments:

NSD
A similar structure is also reported for the compound U3As4 (see entry #0.169). An alternative model with different values for the spin of U was undistinguishable. This one was considered more probable by comparison with U3As4.

Comments (symmetry):

1k magnetic structure
3-dim irrep active. 6 different possible MSGs depending on the order parameter direction (irrep epikernerls). The one realized is one of maximal symmetry.
Ferromagnetic and polar symmetry along the (1,1,1) direction.
