This expression is rigorous at the order considered and can be derived by differentiating the energy derivative of the magnetization in the vicinity of the equilibrium state (formula presented) corresponding to (formula presented) and given by (formula presented). At the upper order, the angle modulation (formula presented) is calculated to be (formula presented), which does not introduce any relevant corrections
