Pressure-Induced Suppression of the Diffuse Scattering in the Model Relaxor Ferroelectric PbMg1/3Nb2/3O3

Résumé

We report an investigation of the relaxor ferroelectric PbMg1/3Nb2/3O3 by combining the external parameter high pressure with x-ray diffuse scattering. The observed total suppression of the relaxor-characteristic x-ray diffuse scattering is unusual and points to important pressure-induced changes in the local order. The observed behavior might well be a general feature in relaxor ferroelectrics under high pressure.
