Preparation and properties of ferroelectric BaTiO3 thin films produced by the polymeric precursor method
(2000-08-01)
Ferroelectric barium titanate thin films were produced by the polymeric precursor method. In this technique, the desired metal cations are chelated in a solution using a hydroxycarboxylic acid as the chelating agent. Barium ...
Multiferroicity in an organic charge-transfer salt that is suggestive of electric-dipole-driven magnetism
(2012-09-01)
Multiferroics, showing simultaneous ordering of electrical and magnetic degrees of freedom, are remarkable materials as seen from both the academic and technological points of view. A prominent mechanism of multiferroicity ...
Local order of Pb1-xLaxZr0.40Ti 0.60O3 ferroelectric ceramic materials probed by X-ray absorption and Raman spectroscopies
(2014-01-01)
This paper reports on the structural characterization of Pb 1-xLaxZr0.40Ti0.60O3 (PLZT) ferroelectric ceramic compositions prepared by the conventional solid state reaction method. X-ray absorption spectroscopy (XAS) and ...
Electrical properties of a composite of Polyurethane and ferroelectric ceramics
(1998-12-01)
Ferroelectric ceramic particles based on lead titanate zirconate (PZT) were dispersed in a polymer matrix based on castor oil. After the poling process, the pyroelectric activity of this composite was measured using a ...
Ferroelectric properties of mechanically synthesized nanosized barium titanate
(Taylor & Francis Ltd, 2005-01-01)
Barium titanate ceramics were prepared through mechanochemical synthesis starting from fresh prepared barium oxide and titanium oxide in rutile form. Mixture of oxides was milled in zirconia oxide jar in the planetary ...
Dielectric relaxation and relaxor behavior in bilayered perovskites
(American Institute of Physics (AIP), 2009-06-29)
Sr(0.5)Ba(0.5)Bi(2)Nb(2)O(9) ferroelectric ceramics exhibit a complex dielectric behavior, showing typical relaxor behavior. The relaxation processes are described by the Cole-Cole model [K. S. Cole and R. H. Cole, J. Chem. ...
Non-Linear Dielectric Properties of PLMN-PT Relaxor Ferroelectrics
(Taylor & Francis Ltd, 2008-01-01)
Recent investigations on the non-linear (NL) dielectric properties of relaxor ferroelectrics systems, not only as ceramic bodies, but also, in thin films, have showed a significant technological and scientific interest. ...
Investigation of Ferroelectric Layered Perovskite Barium Bismuth Tantalate Prepared by Solid-State Reaction
(Taylor & Francis Ltd, 2012-01-01)
Barium bismuth tantalate-BaBiTa2O9 has been prepared by conventional method based on solid-state reaction using BaCO3, Bi2O3 and Ta2O5 as starting materials. It was added excess of 10 mol% of bismuth aiming to improve the ...
Ferroelectric and piezoelectric properties of bismuth layered thin films grown on (100) Pt electrodes
(Elsevier B.V. Sa, 2008-01-21)
The effect of film orientation on piezoelectric and ferroelectric properties of bismuth layered compounds deposited on platinum coated silicon substrates was investigated. Piezo-force microscopy was used to probe the local ...
Dielectric and ferroelectric characteristics of barium zirconate titanate ceramics prepared from mixed oxide method
(Elsevier B.V. Sa, 2008-08-25)
Barium zirconium titanate (BZT) ceramics were prepared by mixed oxide method. X-ray diffraction showed the presence of a single phase while Raman scattering confirmed structural transitions as a function of different Zr/Ti ...
