Síntese e caracterização de compósitos magnetoelétricos particulados de ferritas de Co e Ni e ferroelétricos no CFM
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2010-08-15)
Nowadays, the optimized magnetoelectric coupling in particulate composites is based on the optimization of the processing techniques, which support an integrity interface between the phases, and on the novel combinations ...
Dispersão dielétrica em materiais ferroelétricos.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2004-12-13)
In the last decades, the high frequency dielectric response has been one of
the most studied issues in the ferroelectricity area. The main dielectric
characteristic is the strong dependence of the dielectric parameters ...

Temperature dependence on the electrical properties of Ba(Ti0.90Zr0.10)O-3:2V ceramics
(Elsevier B.V. Sa, 2010-10-01)
Barium zirconium titanate ferroelectric ceramics modified with vanadium Ba(Ti0.90Zr0.10V0.02)O-3 (BZT:2V) were prepared from powders synthesized using the mixed oxide method. The effect of temperature on the structural and ...
Effect of calcium on the structural properties of Ba(1-x)Ca (x) TiO3 particles synthesized by complex polymerization method
(Springer, 2014-04-01)
Ferroelectric materials, such as barium titanate (BaTiO3), have been extensively studied for application in electronic and optical devices. The substitution of Ba by Ca is an effective method to improve the piezoelectricity ...
Synthesis and characterization of BaTiO3 nanoparticles in oxygen atmosphere
(ELSEVIER, 2010-09-03)
A new synthesis route to obtain high-purity barium titanate, BaTiO3, using the sol–gel-hydrothermal
reaction of TiCl4 and a BaCl2 solution in an oxygen atmosphere has been developed. The synthesized
BaTiO3 nanoparticles ...
Preparación y caracterización de nanocompositos en base de Sebs y nanopartículas de BaTiO3, SrTiO3 y (BaTiO3)-(SrTiO3)
(Universidad de Chile, 2018)
El copolímero en bloque de estireno-etileno-butileno-estireno (SEBS) se
