Influence of extrinsic contribution on the macroscopic properties of hard and soft lead zirconate titanate ceramics
(Institute of Electrical and Electronics Engineers (IEEE), 2008-12)
Article
Accés obertIn this work, the contribution of the extrinsic effect to the macroscopic properties in soft and hard lead zirconate titanate ceramics is directly evaluated. Close to the room temperature, poled hard ceramics show an ... -
Nonlinear behavior in a piezoelectric resonator: a method of analysis
(Institute of Electrical and Electronics Engineers (IEEE), 2000-07)
Article
Accés obertTheories used for understanding nonlinear behavior of piezoelectric resonators are usually only valid for a given range of amplitudes. Thus, important discrepancies can sometimes be observed between theory and experiment. ... -
Unexpected dielectric response in lead zirconate titanate ceramics: The role of ferroelectric domain wall pinning effects
(2007-07)
Article
Accés obertTemperature dependent dielectric response has been measured in Pb(Zr1-xTix)O-3 ceramics. Samples of different compositions (x=0.40, 0.47, and 0.60), pure and doped with Nb-or Fe, were studied at temperatures between 15 and ... -
