摘要：
The structure of the relaxer ferroelectric Pb(Mg1/3Nb2/3)O-3 crystal was studied with the X-ray single crystal diffraction at 110, 224 and 293 K. The remarkable redistribution of the reflections intensifies at low temperatures was observed. The structure of the low temperature phase is described with the model of the substantially nonuniform displacements of the lead ions using the derived analytical expression of the scattering form-factor. The structure refinement shows the good agreement between the model and the experimental data at low temperatures.
