NPD
Above 6K, up to 26K, the spins orientate along b, with a single irrep active and a higher MSG (see #1.205)
;

;
1k magnetic structure
Two different irreps active
The x component of the Dy spin (Table 2 of the reference) has been corrected and given a negative sign to make it consistent with Figure 7 of the same reference.
Collinearity is forced by the MSG
