Abstract : The current study investigates the magnetic, electrical, and dielectric characteristics of barium ferrite nanoparticles doped with Sr and Co metals, produced using the microwave gel process. X-ray diffraction (XRD) was employed to analyze the crystalline phases of the prepared materials. The XRD data confirmed that the Sr and Co were successfully incorporated into the BaFe12O19. The dielectric permittivity and ac conductivity of pristine and doped BaFe12O19 nanoparticles have been measured as a function of frequency and temperature. Compared to pristine barium ferrites, Sr and Co-metal-doped barium ferrite nanoparticles exhibit stronger ferromagnetic behavior and increased magnetization. As Sr and Co metal-doped barium ferrite nanoparticles have improved magnetic and dielectric properties, they may be used in magnetic storage devices and absorbing materials, paving the way for exciting new applications in these fields.
