Abstract : The influence of a dynamic magnetoelectric interaction on TE and TM polaritons in a ferrimagnet in IR region of the spectrum has been considered. Frequency dispersions of dielectric and magnetic tensors were taken into account. Spontaneous magnetization induces an electric gyrotropy in a ferrimagnet and the additional radiant TM mode. In the presence of a constant electric field the possibility of a resonant interaction and transformation of the TM polaritons into the TE one and vice versa was predicted.
