Abstract
Due to the complexity of the problems regarding the mechanism of occurrence of ferroelectricity in various ferroelectrics, the interpretation of the Mössbauer spectra and the derivation of some correct information from them is a difficult task which has to take into account the peculiarities of the given ferroelectric. From this point of view, in this paper the results obtained by means of Mössbauer spectroscopy investigations in ferroelectrics are reviewed, underlying the derived information on the lattice dynamics and changes of the electric properties and crystalline structure of ferroelectrics passing through the critical points.
