Abstract:

In this study, multiphase nanocomposites were synthesized through a three-phase pathway. The ferrite phase, (Mg0.5Cd0.5Fe2O4) [MCFO], enhances the material's magnetic and structural properties. The ferroelectric phase, [Pb(1/3BaLi2/3) O3+PbTiO3] [PBLTO], exhibits dielectric loss, stores electrical energy, and polarizes. Dual-phase compounds: [0.25(Mg0.5Cd0.5Fe2O4) + 0.75 [Pb(1/3BaLi2/3)O3+PbTiO3]] [A1] and [0.45(Mg0.5Cd0.5Fe2O4) + 0.55 [Pb(1/3BaLi2/3)O3+PbTiO3]] [A2], were created by varying weight ratios of ferrite concentration. These compounds bridge the gap between the ferrite and ferroelectric phases and approach offers several advantages over traditional methods, including enhanced control over the morphology and properties of the resulting. The synthesis employed the chemical co-precipitation method at an annealing temperature of 550°C for two hours, the structural properties such as lattice constants (a, c), physical density (ρa) and density by X-ray diffraction (ρx-ray). The findings evidenced an increase in the lattice constant attributed to differences in atomic radii of elements, impacting X-ray intensity. Rietveld refinement analysis indicates that the space group for ferroelectric compounds is Fd-3 m, while for ferrite compounds it is P4/mmm. Furthermore, the study revealed that real and imaginary dielectric constants, as well as dielectric losses, demonstrate enhanced performance with increasing frequency at lower frequencies, aligning with the characteristic behavior observed in ceramic materials.

The saturation magnetization value remains relatively constant in the MCFO, A1, and A2 models, despite the decrease in saturation magnetization values with higher ferroelectric phase content (BTO). This suggests that the magnetic field value for saturation magnetization is not significantly affected by the ferroelectric phase content.
