Pressure-induced suppression of the diffuse scattering in the model relaxor ferroelectric PbMg1/3Nb2/3O3 -: art. no. 257601

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.
