The discovery of dispersionless spin waves in antiferromagnets initiates new areas of research important for applied applications. It has been established that the excitation spectrum of the antiferromagnet Fe₂O(SeO₃), which is a new implementation of the sawtooth chain system, and the three-dimensional Mn₂OBO₃ contain branches of high-energy and low-energy spin waves with almost no spatial dispersion. Structures that have dispersion-free spin excitations are the most important for applied applications as process materials for magnonics devices.
