Annotation
Based on the model having regard to quadrupole interaction, magnetic properties of antiferromagnets consisting of two and four magnetic sublattices have been investigated. Resonance spectra conditioned by exchange interaction have been found. It is shown that the frequencies of spin waves have an acoustic and an optical branch.
