Lattice dynamics of the fluoride scheelite CaZnF4

2000

The lattice dynamics of the fluoride scheelite CaZnF4 have been investigated by means of infrared reflectivity and Raman scattering. The measured phonon modes have been assigned to the various irreducible representations of the point group of the crystal. The phonon dispersion curves, density of states and sound velocities have been calculated within a rigid-ion model based on experimental zone-centre phonons.
