Below 67K another magnetic phase exists where the Co spins adquire a z-component with a different k-vector.
See (Morrow et al., J. Amer. Chem. Soc. 135, 18824 (2013)) for a completely different model for this phase (see #1.243). Not only the spin arrangement differs, but also the underlying space group for the atomic positions.
A propagation vector (0,1,0) is reported, but for the B-centered unit cell used, this vector is equivalent to (0,0,0).
