▪ Abstract This article reviews the defect chemistry of perovskite ferroelectric oxides such as
barium titanate and lead zirconate titanate. Such metal oxides are being considered for a …

The dielectric response of hard (Fe-doped) and soft (Nb-doped) rhombohedral Pb (Zr 0.58 Ti
0.42) 1− x Me x O 3 (⁠ Me= Fe or Nb) ceramics was studied at subswitching conditions over …

The dielectric properties of Ba 0.8 Sr 0.2 TiO 3 ceramics doped with Mg from 0.5 to 10 mol%
have been investigated systematically. Two effects of Mg do** on the dielectric properties …

It is shown that the phase angle of the third harmonic of polarization response (δ 3) is very
sensitive to the aging state of hard, Fe-doped lead zirconate titanate [Pb (Zr, Ti) O 3 or PZT] …

A new concept of polarization reversal and domain dynamics in modified ferroelectrics is
presented. Accordingly, clusters with a reversed polarization within ferroelectric domains are …

High piezoelectric properties and superior thermal stability are both important indicators of
piezoelectric ceramics serving at high temperature. However, since these properties are …

Abstract Mn-doped PIN-PMN-PT ceramics were 90%[001] C textured by reactive templated
grain growth (RTGG) with 5 vol% BaTiO 3 microplatelets. Hardened properties such as high …

Configuration of domain walls in undoped and Fe+ 3-doped lead zirconate titanate (PZT)
ceramics at the morphotropic phase boundary has been investigated by the transmission …

In multiferroic BiFeO 3 thin films grown on highly mismatched LaAlO 3 substrates, we reveal
the coexistence of two differently distorted polymorphs that leads to striking features in the …

The dependence of polarization switching on thermal histories has been investigated for K1-
modified lead zirconate titanate PZT ceramics by Sawyer–Tower polarization methods. It …
