Magnetic helix in Mn O2

Two targets are aimed at in this study: i) to show how the consistency principle basis of representations operates in practice, and (ii) to investigate possible magnetic incommensurate structures using the earlier theory of induced representations. The method and the results are considerably different from those obtained on the basis of the Lifshits invariants.The effect of smoothing the exchange energy spectrum on involving non-exchange interaction is found. The role of the dipole interaction in the orientation of the magnetic helix is revealed
