Study of the dielectric response of rare-earth modified pzt ferroelectric ceramics-an approach to the diffuse phase transition
(2018-01-01)
Ferroelectric systems have been widely studied during the last 40 years because of their excellent physical properties, which make them promissory materials for technological applications. In special, the lead zirconate ...
Absence of relaxor-like ferroelectric phase transition in (Pb,Sr)TiO3 thin films
(Springer, 2005-02-01)
We have performed dielectric and micro-Raman spectroscopy measurements in the 298 - 673 K temperature range in polycrystalline Pb0.50Sr0.50TiO3 thin films prepared by a soft chemical method. The phase transition have been ...

New features of the morphotropic phase boundary in the PbZrO 3-PbTiO3 system: A Raman spectroscopy study
(Taylor & Francis Ltd, 2002-01-01)
In this work we present a Raman study of PbZr1-xTi xO3 ceramics with composition values close to the morphotropic phase boundary region. The analysis of the Raman spectra leads to the determination of the monoclinic phase ...
Dielectric properties of Pb Nb2 O6 ferroelectric ceramics at cryogenic temperatures
(2007-08-17)
Complex dielectric permittivity measurements in Pb Nb2 O6 ceramics were performed in a frequency and temperature range of 1 kHz-1 MHz and from 15 to 900 K, respectively. The results revealed two dielectric anomalies showing ...

Dynamical behavior of the phase transition of epitaxial BaTiO_3 from atomistic simulations
(Elsevier Science, 2009-10-01)
Using an atomistic shell model we study the temperature dependence of the ferroelectric properties of BaTiO3 under biaxial compressive strain applicable to growth on perovskites substrate. Molecular dynamics simulations ...
Effect of strontium addition on ferroelectric phase transition of PZT thin films prepared by chemical route
(Springer, 2009-06-01)
The dependence of ferroelectric phase transition temperature as a function of strontium substitution in lead titanate zirconate thin films (referred here as PSZT) on platinum-coated silicon substrates was investigated. The ...
