Czechoslovak Journal of Physics B Aims and scope

Abstract

In the present paper a three-body potential model (TBPM) has been employed for the analysis of dielectric behaviour of NaCl-NaBr and and KCl-KBr mixed crystals with varying compositions. The physical properties like dielectric constants (ɛ 0 andɛ ∞), optic mode frequencies (Ω OLO andΩ TO), effective charge parameter (e *s ), optic mode Grüneisen parameters and strain derivatives ofɛ 0 andɛ ∞ dielectric constants have been calculated. The results achieved in the present study are found in fairly good agreement with the available experimental data. The results obtained by previous investigators are also shown for the sake of comparison.
