Collective dynamics of domain walls: An antiferromagnetic spin texture in an optical cavity

Spin canting and complex spin textures in antiferromagnetic materials can be described terms of Dzyaloshinskii-Moriya interactions (DMI). Values for DMI parameters are not easily measurable directly, often inferred from other quantities. In this work, we examine how domain wall dynamics an optomagnonic system display unique features directly related to the existence DMI. Our results indicate that presence enables with cavity photons a geometry which otherwise allows no magneto-optical coupling, on hand modulates frequencies where coupling is already realized absence This result may used measure constant experiments by comparing resonances obtained different polarizations exciting field.
