This study investigates the structural, microstructural, electronic, and magnetic properties of lithium-doped magnesium ferrite nanoparticles (Mg1-xLixFe2O4) with varying lithium concentrations (x = 0, 0.005, 0.01, 0.015, 0.02, 0.025, 0.03).Samples were synthesized via solution combustion synthesis and characterized using X-ray diffraction (XRD), SEM (SEM), energy-dispersive X-ray spectroscopy (EDX), XPS, and Mossbauer spectroscopy.XRD results confirm the formation of a single-phase spinel cubic structure, with a decrease in lattice parameters and crystallite size observed as lithium content increases.SEM anal. reveals uniform and homogeneous particle distribution, with a slight refinement in grain size with higher lithium doping.EDX confirms the presence of magnesium, iron, and oxygen, but lithium detection is limited due to its low at. number and associated X-ray energy.XPS anal. indicates the chem. surface states of the composites, showing major photoemission peaks for Mg, Fe, and O, with a weak lithium signal due to low photoemission cross sections.Mossbauer spectra indicate superparamagnetic behavior at room temperature, transitioning to Zeeman splitting at 15K, providing insights into the local environments of Fe3+ ions.The findings highlight the impact of lithium doping on the structural, electronic, and magnetic properties of MgFe2O4, suggesting potential applications in magnetic storage devices and catalysis.
