    Polar lattice vibrations and phase transition dynamics in Pb(Zr1-xTix)O3.

  • Original language description

    Infrared (IR) reflectivity spectra of nominally pure Pb(Zr1-xTix)O3 ceramics with different Ti/Zr concentration (x = 0.42 ? 0.58) were measured and evaluated along with the time-domain THz transmittance spectra in the temperature range 10 ? 900 K. The temperature dependence of the low-frequency vibrations, related to Pb atoms, was analyzed in terms of two overdamped modes ?a soft mode and an anharmonic hopping central mode? in the cubic and high-temperature ferroelectric phase, and three main vibrationsin the low-temperature ferroelectric phase with the doubled unit cell: two E-symmetry modes (the soft mode and a mode corresponding to anti-phase vibrations of neighbouring Pb atoms in the THz range), and the antiferrodistortive mode producing the anti-phase tilts of the oxygen octahedra. The last bare mode is not IR active, but it becomes activated by coupling with the soft mode.
