Microwave Combustion Synthesis of La1-xGdxFeO3 (x = 0 to 0.25) Nanoparticles: Structural, Magnetic, Vibrational, Morphology and Optical Behavior

Abstract

La 1 − x Gd x FeO 3 (x = 0 to 0.25) nanoparticles are prepared by microwave combustion process (MCP) with L-alanine as a fuel. The synthesized samples are con rmed by different instrumental characterization for evaluating the nanostructured materials such as XRD, TEM, SAED, XPS, FE-SEM, EDX, FTIR, DRS-UV and VSManalysis.XRD and FT-IR are con rmed that lanthanum ferrite was orthorhombic structure with average crystallite size ranged 57.8 to 37.9 nm. The energy gap values were estimated using UV-vis spectra and it is in the range between 2.17 and 2.43 eV. The elements like Gd, La, Fe and O are present in EDX and XPS analysis. FE-SEM images reveal aggregated spherical morphology. VSM analysis are shows strong ferro magnetic behavior of La 1−x Gd x FeO 3 nanoparticles. The M s and M r values are in the range between1.06 to 1.71and 1.94 to 6.53 emu/g for La 1−x Gd x FeO 3 respectively.
