Effect of Lanthanum Additive on the Structural, Magnetic, and Morphological Properties of LaxNi1-xFe2O4 Ferrite Prepared by Sol-Gel Method
Spinel ferrites are valued for their tunable electrical and magnetic properties. Rare-earth substitution, such as with La3+, is known to modify their cation distribution and magnetic interaction. In this study, LaxNi1-xFe2O4 nanoparticles (x = 0.0, 0.5, 0.7, and 0.9) were synthesized via the sol-gel method. Their prope...
