In chiral magnets, nontrivial spin textures can be realized due to the relativistic spin-orbit Dzyaloshinskii-Moriya interactions between the magnetic moments of unpaired electrons. In particular, a helical magnetic structure can be formed, in which magnetic moments spiral around the helical axis. Here, the authors demonstrate that collective spin excitations of the helical structure (helimagnons) can couple strongly to microwave cavity photons, resulting in the formation of a hybrid state -- the helimagnon polariton.
