The inter-metallic B20 compound MnSi is of great interest as a magnetic model system exhibiting helical spin ordering and topologically non-trivial spin correlations. The application of a small magnetic field leads near TC = 29 K to the formation of a skyrmion crystal which is a 2D hexagonal lattice perpendicular to the applied field composed of magnetic vortices (skyrmions). These vortices are stable due to their topology and therefore of high technological interest in terms of data storage. In fact it was shown that it is possible to write, read and delete individual skyrmions in an ultra thin magnetic film. To understand this novel type of magnetic texture it is crucial to study the associated spin waves - the skyrmimagnons - as their dispersion directly reveals the underlying interaction parameters.
