Soft antiferroelectric fluctuations in morphotropic PbZr1-xTixO3 single crystals as evidenced by inelastic x-ray scattering
Original language description
Lattice dynamics of a PbZr1-xTixO3 single crystal with composition close to the morphotropic phase boundary has been investigated by inelastic x-ray scattering. Dispersion curves of the lowest frequency transverse optic and the transverse acoustic phononmodes propagating alog the [100] direction have been determined in the high-temperature paraelectric phase as well as in the room-temperature monoclinic phase. The measurement also reveals that upon cooling from the paraelectric to monoclinic phase, thespectral response of the M5, zone boundary phonon mode associated with antiferroelectric vibrations of lead ions is progressively transforming to a broad central mode. This indicates a crossover from vibrational to relaxational-type dynamics. The existence of this phenomenon previously observed in relaxor materials is a striking result for PZT and it is believed to arise from the nanoscale structural inhomogeneity of these materials.
