Phonon dispersion calculations using the Vaks model in antiferroelectric lead zirconate
The calculations of low-energy phonon dispersion relations in lead zirconate (PZ) have been carried out using the Vaks model. This model takes into account only five low-energy phonon modes and their interactions. It has been shown that this model allows to achieve good agreement not only between ca...
