Microstructural, Morphological, and Magnetic Features of the Triple Perovskite Oxide La3Mn2FeO9
Abstract
Triple perovskite La3Mn2FeO9 powder was synthesized via the sol gel method. The microstructural, morphological and magnetic features of the prepared perovskite sample were examined by means of X‑ray diffraction (XRD), filed-emission scanning electron microscopy (FE-SEM), and vibrating sample magnetometry (VSM). The XRD pattern was refined using the MAUD software based on the Rietveld program. The results confirmed that the sample crystallized in a trigonal structure, with a crystallite size measuring approximately 257 ± 5 nm and a microstrain of about 0.16%. The FE-SEM image revealed spherical like-particles with an average grain size in the vicinity of 514 nm. The VSM curve revealed that the prepared La3Mn2FeO9 powder exhibited a ferromagnetic behavior, and subsequent fitting using the law of approach to saturation revealed a saturation magnetization of 1.156438 ± 0.00384 emu/g.
