“…A cylindrical mesh may in principle constitute a more natural way to model such a geometry, but the use of a sufficiently large number of quadrilateral cells still represents an alternative valid approach. 30 While we did not observe a dependence of our results on the simulation cell size, we emphasize that selected states such as the multi-domain configurations in Fig. 2 may be related to the existence of several local minima of similar energy and hence depend on the initial state.…”

Synthetic antiferromagnet (SAF) nanostructures with interfacial Dzyaloshinskii-Moriya interaction can host topologically distinct spin textures such as skyrmions and thus are regarded as promising candidates for both spintronics and magnonics applications. Here, we present comprehensive micromagnetic simulations of such material systems and discuss the rich phase diagrams that contain various types of magnetic configurations. Aside from the static properties, we further discuss the resonant excitations of the calculated magnetic states which include individual skyrmions and skyrmioniums. Finally, the internal modes of SAF skyrmion clusters are studied and discussed in the context of magnetic sensing applications based on the dynamic fingerprint in broadband ferromagnetic resonance measurements.
