Abstract
Calcium hexaferrite (CaFe12−xBixO19, x=0.2–0.8) was successfully brewed through a microwave-induced sol–gel auto-combustion technique with Bi3+ as a substitute. The impact of added Bi3+ ions on the structure, morphology, magnetic, and dielectric properties of calcium hexaferrite was analyzed using an X-ray powder diffractometer (XRD), Field emission scanning electron microscopy (FE-SEM), vibrating sample Magnetometry (VSM), Fourier transforms infrared spectroscopy (FT-IR), and impedance study. The peak position in the XRD pattern confirms the development of single-phase hexagonal ferrite nanoparticles with a space group of P63/mmc and an average crystalline size of 46–56 nm. Magnetic analysis revealed that when the Bi3+ ion is added to Ca ferrite, the material's coercive force improves, but the saturation magnetization decreases. The dielectric constant, electric conductivity, and loss tangent of the substance were determined for frequencies ranging from 20 Hz to 1 MHz, indicating appropriate for various applications, including permanent magnets and high-density magnetic recording media.
