Lead titanate zirconate (PZT) and lanthanum-modified lead titanate zirconate (PLZT) ferroelectric ceramics have been great scientific and technologic interest, due to the possibility of your physics properties can be optimized and adequated for specific technologic applications. Scientifically, the anelastic characterization of the phase transitions have a fundamental importance to understand the phenomenology and behavior of the intrinsic properties. In this work, the phase transition exhibit by PZT and PLZT were studied, for Zr/Ti ratios of 40/60 and 65/35 for PZT, and Zr/Ti ratio 65/35 for PLZT, with lanthanum concentration between 5 mol-% and 9 mol-%, by mechanical spectroscopy technique. The nelastic spectra as a function of temperatur...
