Tailoring Structure, Morphology, And Magnetic Behavior in Eu-Doped Bafeo₃ Perovskite Nanomaterials

Abstract

This study examines the influence of Europium (Eu) doping on the structural, morphological, and magnetic properties of barium ferrate (BaFeO₃), a perovskite oxide with potential for use in advanced technologies. BaFeO₃ samples were synthesized via the solution combustion method, a simple, rapid, and energy-efficient technique that produces fine, uniform powders with high purity. X-ray diffraction (XRD) analysis confirmed the formation of a single-phase cubic spinel perovskite structure. As the Eu doping concentration increased (0%, 5%, and 9%), a gradual decrease in crystallinity was observed, suggesting lattice distortion without any phase change. Field Emission Scanning Electron Microscopy (FESEM) showed a reduction in particle size and noticeable changes in surface morphology at higher doping levels. Magnetic measurements carried out using a Vibrating Sample Magnetometer (VSM) revealed significant changes in magnetic behavior due to Eu doping, including variations in saturation magnetization and coercivity. These findings indicate that Eu doping is an effective approach to modify and improve the physical and magnetic characteristics of BaFeO₃, making it more suitable for future functional, magnetic, and electronic applications.
