Abstract

Diffuse and Bragg scattering of synchrotron radiation on single crystal PMN relaxor has been collected as a function of pressure. The relaxor-specic diffuse scattering (DS) is observed for p < 40 kbar and successfully parametrized with the thermal DS-like model of polar correlations. An increase of pressure does suppress the polar correlations in a specic glass-like relaxor state, and above ~40 kbar a new non-polar R-phase becomes stable. We propose a phenomenological model accounting for off-center displacements of lead ions; together with previous reports these findings map the relaxor state to a specifc area of phase diagram.

Keywords: Relaxor ferroelectrics; diffuse scattering; Landau theoryn
