    • When D′ ≠0, we have to transform the operators back onto the original frame: the 120° order transforms onto a weak ferromagnet. In fact the classical energy difference between the weak ferromagnet and the coplanar 120° state is only of order D′2, and one must include second-order exchange anisotropies to actually predict the form of order (Ref.).
