Spin Wave Power Flow and Caustics in Ultrathin Ferromagnets with the Dzyaloshinskii-Moriya Interaction

We examined how the Dzyaloshinskii-Moriya interaction (DMI) influences the flow of spin waves in ultrathin films using analytical theory and micromagnetics simulations. With a point source field excitation, we find a number of different propagation regimes, such as caustics and interference patterns that are asymmetric as a result of the DMI.
