Comments:

NPD.
Ferromagnetic. Nn detectable ordered Ni moment was found.

Comments (symmetry):

1k magnetic structure
two 1-dim irreps as primary
The a and c ferromagnetic components belong respectively to mGM3+ and mGM2+ of the parent Cmcm structure. Their simultaneous presence lowers the symmetry to C2'/c'.
