Lattice dynamics and domain wall oscillations of morphotropic Pb(Zr,Ti)O3 ceramics
Original language description
of morphotropic Pb(Zr1xTix)O3 (PZT) ceramics with compositions PZT 52/48 and 53/47 were studied by a broadband spectroscopy approach, using Raman, far-infrared, time-domain terahertz (THz), and microwave spectroscopies. A careful evaluation of the evolution of phonon parameters with temperature clearly revealed only two macroscopic phase transitions of intrinsic origin, driven by phonons: the ferroelectric one at high temperatures near 650 K (driven by an anharmonic soft mode at THz frequencies coupled to a weak component at higher frequencies, ω ∼ 70 cm1) and a transition to an antiferrodistortive phase around 400 K, signaled by a new peak (ω ∼ 60 cm1) that appeared in the infrared and Raman spectra. This peak confirmed the onset of the antiphase tilt of the oxygen octahedra and the doubling of the unit cell, as well as the splitting of the B1-E doublet in the Raman spectra.
