Abstract

The Microwave induced sol-gel auto-combustion process was used to make lead hexaferrite, PbFe12-xBixO19 (x=0.2 to 0.8), with Bi3+ as a replacement. X-ray powder diffractometer (XRD), scanning electron microscopy (SEM), vibrating sample Magnetometry (VSM), Fourier transform infrared spectroscopy (FT-IR), and Impedance analysis was used to test the impact of added Bi3+ ions on the structure, morphology, magnetic, and dielectric properties of lead hexaferrite. Single-phase hexagonal ferrite nanoparticles with average crystalline sizes of 43 to 59 nm were achieved with the space group of P63/mmc. The magnetic analysis revealed that when the Bi3+ ion is supplemented in the Pb ferrite,the coercive and saturation magnetization of the material was amplified. The substance's dielectric constant, electric conductivity, and loss tangent were calculated for frequencies of 20 Hz to 10 MHz, indicating that it is appropriate for wide applications like permanent magnets, high-density magnetic recording media.
