Abstract
The antiferromagnetic resonance frequencies, the high-frequency magnetic susceptibility tensor, and the amplitudes of normal oscillations of a quasi-two-dimensional four-sublattice antiferromagnet with a relativistically noncollinear structure are found. A comparative analysis of the dynamical properties of low-dimensional and three-dimensional four-sublattice antiferromagnets is performed. It is shown that their dynamical behavior differs substantially, and in addition the properties of the low-dimensional multisublattice systems cannot be described on the basis of models with a smaller number of magnetic sublattices.
