Abstract
The nano-sized BaTiO 3 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 xBaTiO 3 + (1 − x)NiCuZnFe 2O 4 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 BaTiO 3 content in the composites. The frequency variation dielectric constant ( ɛ), dissipation factor ( D), initial permeability ( μ i) 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).
