Understanding the spin-wave excitations of chiral magnetism is important to confirm such exotic magnetic order. Here, the authors obtain the spin wave spectrum for a given magnetic structure from Monte Carlo simulations and analyse the signatures when a ferromagnetic film undergoes a transition from a skyrmion crystal to a helical phase.
