Comments:

NPD. Structure and magnetic-structure refinements were performed with GSAS-II.
Positional structuee from a determination at 300K

Comments (symmetry):

Powder NPD could not distinguish the [001] and [111] moment directions; the [111] model was selected using DFT total-energy calculations.
