Abstract
LaFeO3 nanoparticles of different sizes are prepared by varying the molar concentration of oleic acid to metal nitrate using emulsion combustion method. X-ray diffraction analysis confirms that LaFeO3 nanoparticles are crystalline in nature with an orthorhombic structure. The average particle size and saturation magnetization decreases from 56 to 32 nm and 0.20 to 0.08 emu/g, as molar concentration of oleic acid to metal nitrate increases from 0.25 to 1. The Fourier transform infrared (FTIR) spectra show the lower frequency bands are assigned to Fe–O stretching vibration (579 cm−1) and O–Fe–O deformation vibration (475 and 400 cm−1). The experimental results suggest that molar concentration of oleic acid to metal nitrate plays an important role in the particle size and magnetic property of combustion synthesized lanthanum ferrite nanoparticles.
