Dielectric properties of BaTiO3 and La doped BaTiO3 ceramics
Pramana, 1991The dielectric constant and loss tangent of barium titanate and barium titanate doped with 0.4% (mole) La ceramics have been studied in the frequency range 22 KHz-70 MHz at room temperature and in the temperature range 20°C–170°C at 22 KHz using aQ-meter.

Conduction Mechanisms in Multiferroic Multilayer BaTiO3/NiFe2O4/BaTiO3 Memristors
Journal of Electronic Materials, 2017Memristive devices and materials are extensively studied as they offer diverse properties and applications in digital, analog and bio-inspired circuits. In this paper, we present an important class of memristors, multiferroic memristors, which are composed of multiferroic multilayer BaTiO3/NiFe2O4/BaTiO3 thin films, fabricated by a spin-coating ...

Phase transitions in BaTiO3 thin films and BaTiO3/BaZrO3 superlattices
Journal of Applied Physics, 2014Using pulsed laser deposition, we grew a ferroelectric [BaTiO3]Λ/2/[BaZrO3]Λ/2 (BT/BZ) superlattice with a stacking periodicity of Λ = 256 Å and a BT single film on a La1/2Sr1/2CoO3-buffered (001)MgO substrate, and then studied the phase transitions of these materials.

Direct observation of BaTiO3 microcrystallites in thin amorphous BaTiO3 films
Applied Physics Letters, 1991Well separated BaTiO3 microcrystallites were observed by transmission electron microscopy (TEM) in rapidly annealed, amorphous BaTiO3 thin films. The crystallization temperature for amorphous BaTiO3 is between 400 °C and 500 °C.

Influence of BaTiO3 on Magnetic and Transport Properties of La0.7Sr0.3MnO3-BaTiO3 Nanocomposite
Journal of Superconductivity and Novel Magnetism, 2018La0.7Sr0.3MnO3 (LSMO)-BaTiO3 (BTO) nanocomposites have been synthesized by adding different amounts of BTO using the sol-gel method. The structural analysis confirms that both phases coexist in the composite samples with the rhombohedral and tetragonal structure for LSMO and BTO, respectively.

Dielectric and optical properties of BaTiO3/SrTiO3 and BaTiO3/BaZrO3 superlattices
Journal of Applied Physics, 2002BaTiO 3 (BTO)/SrTiO3 (STO), and BaTiO3/BaZrO3 (BZO) artificial superlattices were fabricated by the molecular beam epitaxy process and their dielectric properties and refractive indices were measured. Superlattices formed on Nb-doped STO substrates showed large leakage currents in comparison with those on pure STO substrates.

Abstract Highly (110)-oriented trilayered BaTiO 3 (25 nm) /(Na 0.5 Bi 0.5 ) 0.94 Ba 0.06 TiO 3 (300 nm) / BaTiO 3 (25 nm) thin films were deposited on Pt/Ti/SiO 2 /Si substrates via chemical solution deposition. It was found that the inserted bottom BaTiO 3 layer between Pt and (Na 0.5 Bi 0.5 ) 0.94 Ba 0.06 TiO 3 is very effective for promoting ...

Dispersion of BaTiO3 powders (part I)
Ceramics International, 1984Abstract The fundamental properties of BaTiO 3 dispersions in pure organic liquids and water were studied by sediment volume and contact angle measurements. The liquid groups included alcohols, aldehydes, acids, esters, ketones, ethers, hydrocarbons, and water.

Journal of Electroceramics, 2006
An attempt was made to retard the dissolution of Ba ions from BaTiO3 by coating Y compounds on the BaTiO3 particle surface. A hysteresis in the electrokinetic behavior of as-received BaTiO3 occurred during sequential acid and base titrations, while there was no hysteresis in the Y-coated BaTiO3. In the bare BaTiO3, dissolved Ba ions are adsorbed and/or
