Abstract: he effect of hydrostatic pressure on phase transitions in lead hafnate (PbHfO$_{3}$) has been studied by the methods of X-ray diffraction and X-ray diffuse scattering. The measurements were performed in the temperature range of 182 $<T<$ 316$^\circ$C and the pressure range of 1.6 $<P<$ 2.6 GPa. Four regions characterized by different X-ray diffraction patterns and corresponding to an antiferroelectric phase, phases with a long-wavelength modulation of the lead sublattice, and phases with different distortions of the oxygen sublattice are identified. In the temperature region immediately above the region of phases with a long-wavelength modulation, a temperature-dependent maximum in the distribution of diffuse scattering was detected, which means that such a modulation is formed due to condensation of an incommensurate soft mode.
Keywords: antiferroelectricity, lead hafnate, high pressure, order parameters, diffuse scattering.
