Exploring the Structural, Surface Morphological and Magnetic Properties of Eu Doped MnFeO3 Nanomaterials

Abstract

This study explores the impact of Europium (Eu) doping on the structural, morphological, and magnetic properties of manganese ferrite perovskite (MnFeO₃), a material with significant potential for advanced technological applications. MnFeO₃ was synthesized using the solution combustion method, an energy-efficient technique that enables the production of fine powders with controlled purity and morphology. X-ray diffraction (XRD) analysis confirmed the formation of a spinel cubic perovskite structure. A noticeable decrease in crystallinity was observed with increasing Eu doping concentrations (0%, 5%, and 9%), suggesting lattice distortion without altering the overall phase structure. Field emission scanning electron microscopy (FESEM) revealed a reduction in particle size and notable changes in surface morphology with higher Eu content. Energy dispersive X-ray (EDX) spectroscopy confirmed the successful incorporation of Eu into the MnFeO₃ lattice, as evidenced by the presence of Mn, Fe, O, and Eu peaks. Magnetic measurements conducted using vibrating sample magnetometry (VSM) showed that Eu doping significantly influenced the magnetic properties of MnFeO₃, leading to variations in both saturation magnetization and coercivity. Overall, the findings demonstrate that Eu doping is an effective approach for tuning the structural, morphological, and magnetic characteristics of MnFeO₃ for advanced functional applications.
