Abstract.

Results of far-infrared transmittance are reported for GdMnO3, a multiferroic perovskite manganite. The spectra allow to obtain position and intensity of the high-frequency electromagnon (~75 cm-1) in this material. We present a comparative analysis of the high- and low-frequency electromagnons across the phase diagram of GdMnO3. The traces of the electromagnon excitation can be detected even deeply in the paramagnetic state, which is attributed to magnetic fluctuations.
