The structural and magnetic characteristics of La0.7Sr0.3MnO3(LSMO), which is produced using sol-gel, solution combustion, and The material's morphology and structure, which define its overall properties, are controlled by the synthesis process; The synthesis begins with metal nitrates as the metal source, citric acid as the chelating agent, propylene glycol as the solvent, and distilled water (DW) as the precursor. With the use of SQUID magnetometry, X-ray photoelectron microscopy (XPS), X-ray diffraction (XRD), and crystallinity, the formation mechanism, crystal structure, Phase composition, and magnetic characteristics are examined. A crystallite size of around 17.9 nm has been confirmed by XRD measurements to be the phase of pure nanocrystalline La0.7Sr0.3MnO3The 300K and 5K magnetic characteristics are studied. La0.7Sr0.3MnO3(LSMO) nanoparticles exhibit superparamagnetic behavior; coercivity and remanence are negligible. The M-H curvesdemonstrate that the samples' nanoparticles have ferromagnetic order, and the Arrott plots suggest that ferromagnetic order increases with increasing particle size.
