Abstract:

For ionic crystals of NaCl and CsCl structures, the volume dependence of the effective ionic charge ( d ln s d ln V) defined by the second Szigeti relation is calculated using low temperature experimental data. The need for experimental data of γT at T→ 0°K is remarked upon. ( d ln s d ln V) obtained independently with a deformation dipole model and a simple shell model. The results are compared. All models tend to give positive values of ( d ln s d ln V), as expected. © 1984.
