Chiral standing spin waves in skyrmion lattice

This work studies the resonance excitations of three-dimensional skyrmions lattice in finite thickness plate an isotropic chiral magnet using spin dynamics simulations. We found that absorption spectra and modes differ from those predicted by two-dimensional model unconfined bulk crystal. The features observed on can be explained formation standing waves, which, contrary to conventional are characterized helical profile dynamic magnetization fixed chirality defined Dzyaloshinskii-Moriya interaction. In this case, susceptibility becomes a function thickness, which gives rise interesting effect manifests itself periodical fading intensity corresponding makes excitation these impossible at specific thicknesses.
