Abstract
The impact of milling and subsequent annealing on the phase evolution, microstructure and magnetic properties of Li0.5SmxFe2.5−xO4 (x = 0, 0.05, 0.1, 0.2) ferrite prepared by mechanical alloying was investigated. X-ray diffraction (XRD), scanning electron microscope, Fourier transform infrared spectroscopy, laser particle size analysis, and vibrating sample magnetometry were employed to characterize the prepared LiSm compound. The structure was evaluated by XRD, confirmed the formation of its single-phase spinel structure. The magnetic properties of the milled nanostructured powder were extensively affected by the annealing temperature. The substitution of samarium significantly influences the magnetic characteristics, proved by magnetization measurements at room temperature.
