Effect of annealing atmosphere on phase formation and electrical characteristics of bismuth ferrite thin films
(Materials Research Bulletin, 2009-08-05) [Artigo]
Bismuth ferrite thin films were deposited on Pt/Ti/SiO(2)/Si substrates by a soft chemical method and spin-coating technique. The effect of annealing atmosphere (air, N(2) and O(2)) on the structure and electrical properties ...
NiTiO3 powders obtained by polymeric precursor method: Synthesis and characterization
(Journal of Alloys and Compounds, 2009-01-22) [Artigo]
Nickel titanate (NiTiO3) powders were synthesized by the polymeric precursor method after thermal treatment at different temperatures for 2h in air atmosphere. The decomposition of the precursors was monitored by differential ...
Ferroelectric and dielectric properties of vanadium-doped Ba(Ti0.90Zr0.10)O-3 ceramics
(Journal of Alloys and Compounds, 2008-10-20) [Artigo]
Ba(Zr0.10Ti0.90)O-3 (BZT) and V substituted BZT ceramics (BZT:V) were prepared by mixed oxide method and polymeric precursor method. The effect of V5+ addition in the BZT lattice was evaluated by X-ray diffraction (XRD) ...
Structure, ferroelectric/magnetoelectric properties and leakage current density of (Bi0.85Nd0.15)FeO3 thin films
(Journal of Alloys and Compounds, 2011-04-28) [Artigo]
In this paper, we report on the structure, ferroelectric/magnetoelectric properties and improvement of leakage current density of (Bi0.85Nd0.15)FeO3 (BNFO) thin films deposited on Pt(1 1 1)/Ti/SiO2/Si substrates from the ...
Effect of niobium dopant on fatigue characteristics of BiFeO3 thin films grown on Pt electrodes
(Journal of Alloys and Compounds, 2009-06-24) [Artigo]
Pure BiFeO3 (BFO) and Nb-doped (BFN) thin films were fabricated by the soft chemical method. The films were polycrystalline when deposited on Pt/Ti/SiO2/Si substrate and annealed at 500 degrees C for 2 h. X-ray diffraction ...
Structural and dielectric properties of Ba0.5Sr0.5(SnxTi1-x)O-3 ceramics obtained by the soft chemical method
(Journal of Alloys and Compounds, 2009-05-27) [Artigo]
Ba0.5Sr0.5(SnxTi1-x)O-3 ceramics with different compositions (x = 0, 0.05, 0.10 and 0.20) were synthesized by the soft chemical method. X-ray diffraction patterns and Rietveld refinements revealed that these ceramics ...
Effect of oxidizing atmosphere on ferroelectric and piezoelectric response of CaBi2Nb2O9 thin films
(Materials Chemistry and Physics, 2010-12-01) [Artigo]
Calcium bismuth niobate (CaBi2Nb2O9 CBNO) thin films were evaluated for use as lead-free piezoelectric in micro-electromechanical systems The films were grown by the polymeric precursor method on Pt/Ti/SiO2/Si (1 0 0) (Pt) ...
Microwave-hydrothermal synthesis of barium strontium titanate nanoparticles
(Journal of Alloys and Compounds, 2010-10-22) [Artigo]
Hydrothermal-microwave method (HTMW) was used to synthesize crystalline barium strontium titanate (Ba(0.8)Sr(0.2)TiO(3)) nanoparticles (BST) in the temperature range of 100-130 degrees C. The crystallization of BST with ...
