    • It is not possible to assign a chirality (or handedness) to a cycloid since the propagation vector and the spiral plane are parallel. Therefore, we refer to the chiral component Mch in order to access the chiral domains.

    • In the case of MnWO4 it is not sufficient to analyze the nearest-neighbor spins in order to explain the ferroelectric polarization along b since the spin-wave dispersion shows that this interaction is not dominating. However summing Eq. over all spin pairs the spiral arrangement with eeasy and b components also generates a ferroelectric polarization along b.
