Parfenov, A. Liberman, I. Gubanova] We have studied vibratory spectra in the range 200-700 cm−1 of Mn−Zn ferrite crystal lattices containing both an iron excess or an iron deficit of up to 8 mole% relative to the stoichiometric compound. We performed a Kramers-Kronig analysis of the reflectance spectra, and a dispersion analysis of the spectra of the dielectric functions. The vibratory spectral band is quite complex. The compositional dependence of the individual component intensities is explained by a cation distribution model. According to this model the manganese cations in the octahedral sites are +3 valence in both iron-poor and iron-rich ferrites.
