Abstract
An x-ray diffraction study of the paraphase of the (PbMg1/3Nb2/3O3)0.6-(PbTiO3)0.4 solid solution has been found to exhibit a clearly pronounced ferroelectric transition. It is shown that Pb2+ ions occupy a special position (000), as opposed to pure PMN and other relaxor ferroelectrics, where they are displaced from it in random directions. The absence of these displacements indicates suppression of frozen-in random electric fields in this compound.
