Title: Dynamical Study Of Phonons In Pbtio3
Author: Freire J.D.
Katiyar R.S.
Abstract: Lattice dynamical formalism, using rigid ion model, was applied to the crystal of PbTiO3 in the tetragonal phase. The model includes long range Coulomb forces and short range axially symectric forces. The radial part of the short range force constants was assumed to be of Born-Meyer type. The parameters of the model were determined through a least squares analysis of zone center and a few zone boundary phonons. Dispersion curves for [100] and [001] directions are presented. © 1981.
