Abstract
A rheological phase reaction method was developed to synthesize the nanocrystalline lanthanum-substituted lithium-nickel ferrites, Li0.25Ni0.5LaxFe2.25âxO4 (x=0.00, 0.025, 0.05, 0.075, 0.10). The structure, morphology, and magnetic properties of the as-prepared Li0.25Ni0.5LaxFe2.25âxO4 ferrites were characterized by powder X-ray diffractometer (XRD), scanning electron microscope (SEM), and vibrating sample magnetometer (VSM). It was shown that Li0.25Ni0.5LaxFe2.25âxO4 ferrites exhibited the single-phase spinel structure. The lattice parameters increased with increasing the La content, whereas the crystallite sizes decreased. The magnetic properties of Li0.25Ni0.5LaxFe2.25âxO4 ferrites were strongly affected by the La content. The saturation magnetization decreased, while coercivity increased with increasing the La content.
