Microwave-Hydrothermal synthesis of BaTiO3 + NiCuZnFe2O4 nanocomposites
چکیده انگلیسی
The nano-sized BaTiO3 and NiCuZn ferrite powders were synthesized using Microwave-Hydrothermal (M-H) system at 160 °C/45 min. The ferroelectric and ferrite phases were confirmed by the XRD and surface morphologies were studied by SEM and TEM. The size of the powders that were synthesized using M-H system was found to be 40-60 nm. The xBaTiO3 + (1 − x)NiCuZnFe2O4 nano-composites were prepared at different weight percentages. The room temperature hysteresis loops were taken on the present composite samples in the field of 5 kOe. The value of coercivity and saturation magnetization was found to be increasing with the decrease of BaTiO3 content in the composites. The frequency variation dielectric constant (ɛ), dissipation factor (D), initial permeability (μi) and quality factor (Q) were studied at room temperature in the frequency range of 1 kHz-1 MHz region. From these studies it was observed that the present composites were useful for the fabrication of Multilayer Chip Inductors (MLCI).
