Manifestation of a series of phase transitions in IR spectra of a multiferroic TbMnO3

We have studied IR transmittance spectra of a multiferroic TbMnO 3 . Three phase transitions ( T N = 43 K, T FE = 28 K, and T Tb = 7 K), which manifest themselves in a shift of the absorption band edge of manganese and in changes in the spectral parameters of lines of f-f transitions of terbium, hav...
