Stable and metastable ferroelectric polarization analyzed by the ramp voltage technique
(2002-12-01)
The study of the stable and the metastable ferroelectric polarization of poly(vinylidene fluoride), PVDF, was performed using two successive equal sign ramp voltages, mediated by a short-circuit period. Rates from 10 V/s ...
The use of pulsed electric acoustic technique for measuring the polarization reversal in ferroelectric ceramic samples
(2002-01-01)
The pulsed electric acoustic technique, PEA, has been usually applied to probe space charge profiles in polymers. Preliminary PEA results using a ferroelectric ceramic are presented. If the reverse applied electric field ...
Dielectric and fatigue properties of Pb(Zr0.53Ti0.47)O-3 thin films prepared from oxide precursors method
(Materials Research Society, 2005-01-01)
Fatigue is an important problem to be considered if a ferroelectric film is used for non-volatile memory devices. In this phenomena, the remanent polarization and coercive field properties degrades in cycles which increase ...

Magnetic properties of acicular ultrafine iron particles
(2002-12-01)
The magnetic properties of acicular ultrafine iron particles are studied. The introduction of high recording densities on recording media has meant a dramatic bit size reduction and track density increase on the media ...
Structural, dielectric and ferroelectric properties of Nb-doped PZT thin films produced by oxide precursor method
(2002-01-01)
Recently, was proposed a chemical method for preparation of ferroelectric thin films based on oxide precursors. In this work, PZT thin films were prepared to attest the viability of this method for cation-substitution. In ...
Magnetoelectric properties of la-modified BiFeO3 thin films on strontium ruthenate (SrRuO3) buffered layer
(2014-01-15)
This paper focus on the magnetoelectric coupling (ME) at room temperature in lanthanum modified bismuth ferrite thin film (BLFO) deposited on SrRuO 3-buffered Pt/TiO2/SiO2/Si (100) substrates by the soft chemical method. ...
