NSD
Position structure except relative coordinates of Tb1 is not given in the reference. Here, the position structure of non-magnetic atoms and cell parameters are taken from a determination at 293K by another work.
FM along b. 
Weak FM canting along b allowed by the MSG is observed. See #0.706 for a NPD study where it is not detected.
