Spin waves are one of the promising candidates for information carriers in future electronic devices. They are applicable in the wide frequency region and reduce energy losses. Now the main challenge is to uncover mechanisms of proper propagation, manipulation, and detection of spin waves. Recent research shows that a magnetic and electric field could manipulate spin dynamics. The last variant opens the possibility to realize different propagation spin-waves in opposite directions, not limited to the magnets with inversion symmetry breaking. It is possible as an external electric field could induce the Dzyaloshinskii-Moriya interaction that changes the spatial distribution of spin waves in the nonchiral magnets. Confirmation of this is already available for ferromagnets, and we provide more in-depth studies of this effect for a two-sublattice antiferromagnet. We use a phenomenological approach based on the Landau-Lifshitz-Gilbert equations to detect spin dynamics. The dependence of spin dynamics on the magnitude of the applied electric field was found.
