1k incommensurate magnetic structure
This spin modulation requires the incoherent superposition of two spin modes, each transforming according to the same irrep mF2 (i.e. two distinct primary order parameters must be involved).
A single spin mode transforming according to the irrep necessarily requires a pi/2 shift between the modulation on the plane xy and the one along z. This would imply a helical spin modulation if both components are present.
The presence of two mF2 spin modes with a phase shift between them reduces the magnetic symmetry from a centrosymmetric MSSG to a non-centrosymmetric one.
