Pressure Dependence of Raman Scattering in Ferroelectrics and Ferroelastics

  • P. S. Peercy

Abstract

Inelastic light scattering at high pressure from soft mode systems is briefly reviewed. Examples of the different types of soft-mode systems in which the pressure dependence of Raman and Brillouin scattering have been investigated are summarized. Special emphasis is given to three important systems: the coupled-proton-optic mode in hydrogen bonded ferroelectrics of the KDP class, the tricritical behavior in the ferroelectric SbSI, and optic-acoustic interactions in the ferroelastic rare-earth pentaphosphates.
