Comments:

NPD
Lattice parameters from a room temperature experiment
A 2k magnetic structure is reported below 140K (see #2.31).
Moment modulus: 1.21
Moment components given here with non-significant digits to yield the reported modulus

Comments (symmetry):

1k magnetic structure
A single 3-dim irrep along a special direction as primary irrep
