Bi0.8Ba0.1Er0.1Fe0.96Cr0.02Mn0.02O3 (BBEFCMO) multiferroic ceramic was synthesized through the sol-gel route. The impact of incorporating various dopants into both A and B sites BiFeO3 investigated, structural, Raman, dielectric, electric, magnetic properties were studied. X-ray diffraction analysis Raman spectroscopy revealed a rhombohedral structure with R3c space group for doped material (BBEFCMO). Dielectric examined across frequency range 102–106 Hz. present exhibits colossal dielectric constant minimal loss tangent, making it suitable applications in energy storage. Furthermore, Cole-Cole type relaxation deduced from imaginary part modulus grain boundary-grain contributions. Overall, this study indicates that substituting ions significantly enhances its properties, as evidenced by measurements.
