Abstract
A layer of an easy-axis antiferromagnet with antisymmetry center is considered. It is shown that the combination of magneto- and electric-dipole mechanisms of the indirect spin–spin interactions gives rise to the previously unknown class of hybrid dipole waves such as exchangeless magnetoelectric magnons and to the spin–spin and spin–dipole resonances accompanying them. The conditions for the formation of these waves are determined.
