Abstract: This article focuses on the production of manganese ferrite (MnFe2O4) magnetic nanoparticles (MNP?s) via green sol-gel auto-ignition process. The structural studies done through X-ray diffraction (XRD), microstructural through transmission electron microscopy (TEM), and vibrating sample magnetometry (VSM) were employed to examine magnetic properties. Investigation of the XRD outlines the development of a cubic spinel geometry deprived of any contamination. The average crystallite size was determined to be in the nanometer range, consistent with TEM results i.e. 32-33 nm. The magnetic entities, including saturation magnetization Ms = 20.57 emu/g, remanent magnetization Mr = 13.30 emu/g, and coercivity Hc = 804 Oe, were extracted from the M-H curve. The nanocrystalline sample displayed a dilute ferrimagnetic behavior. Manganese ferrite nanoparticles demonstrated remarkable oxidative degradation activity towards methyl orange synthetic dye, a compound regularly cast-off in the textile industry and recognized for its struggle to biodegradation.
