Abstract: Effect of plasmon–magnon interaction on the propagation of a hybrid wave along the graphene surface in the graphene–antiferromagnetic insulator system is studied. Three antiferromagnetic materials NiO, FeF$_2$, and MgF$_2$ with different antiferromagnetic resonance frequencies in the terahertz range and different damping rates of magnons are considered. It is found that the plasmon–magnon interaction is manifested in a change in the dispersion relation near the antiferromagnetic resonance frequency, and the efficiency of this interaction depends on the position of the Fermi level in graphene and the damping of magnons.
