2k magnetic structure
6-irrep along a special direction as primary
The star of the active irrep has three k-vectors. This is a 2k model involving two of them. 
A 3k model is also proposed as a possible alternative, fitting equally well the data (see #3.18). 
The also possible 1k model is discarded in favor of these two multi-k models.
