Comments:

NPD
Ferromagnet along a general direction

Comments (symmetry):

1k magnetic structure
Three 1-dim irreps are necessary as primary irreps for this model
The three spin components correspond to three different irreps
Between 66K and 20K a ferromagnetic phase along c is reported (see #0.1047)
