Abstract
Lanthanum-doped nano spinel ferrite compounds were synthesized via normal micelles method, characterized by means of TGA/DSC curves to know calcination temperature and stoichiometry of elements confirmed by EDAX. X-ray diffraction shows well defined cubic spinel structure with secondary phase of ortho ferrite LaFeO3. Lattice parameter exhibited gradual increases with increasing in La3+ ion concentrations due to the larger ionic radii of La3+ ions replace Fe3+ ions. FT-IR spectra recorded in the range of 4000–400 cm−1 to detect vibrational bands. Surface morphology analyzed by SEM, The particle size analyzed by Dynamic Light Scattering, full width half maxima of 311 peak obtained from XRD and TEM analysis, reveals that fine particle nature with little agglomeration and average particle size determined in the range of few nano meters.
