摘要

This study investigated the permittivity properties of BaZn1+xMnxFe12-2xO19 (x = 0.0, 0.4, 0.8, 1.2, 1.6, and 2.0), a compound synthesized via the standard ceramic method, to explore its potential for energy storage and electronic applications. We employed X-ray diffraction (XRD) for phase composition analysis and LCR meter was employed to measure the real and imaginary permittivity across temperatures of 297–530 K and frequencies of 10–100 kHz. The XRD analysis confirmed a pure phase and revealed influences on crystal size, x-ray density, and lattice parameters.The observed Maxwell–Wagner-type polarization enhances the material's low dielectric loss and high permittivity, making it well-suited for EMI shielding and radar-absorbing materials (RAMs). Results showed that Zn–Mn ion concentration improves the dielectric permittivity and positively impacts the thermal stability and Curie temperature, enhancing the material's magnetic stability suitable for energy storage applications. These findings not only underscore and highlight the enhanced material’s suitability of BaZn1+xMnxFe12-2xO19 for energy storage applications but also exhibits strong potential for microwave devices, supercapacitors, high-frequency capacitors, and advanced energy storage devices, electromagnetic interference, and absorbent materials in advanced electronic devices, further broadening its practical applications in green technology.
