摘要

This study investigates the structural, optical, and magnetic properties of double perovskites (DP) structured Ba₂FeMnO₆ (BFMO) synthesized via the solid-state reaction method. Rietveld refinement of X-ray diffraction data confirms the formation of a cubic structure with space group Fm-3 m (#225) and high phase purity. Fourier Transform Infrared (FTIR) spectroscopy verifies the presence of metal–oxygen bonding. UV–Vis spectroscopy and Tauc plot analysis determine an optical band gap of 2.1 ± 0.01 eV. Magnetic measurements reveal room-temperature weak ferromagnetic (FM) behavior. These findings highlight BFMO's potential for room temperature spintronic applications.
