In this study, spinel ferrite nanoparticles CoFe2-xLaxO4 (x = 0, 0.025, and 0.05) were successfully synthesized via a simple co-precipitation method using a 5% NaOH solution as a precipitating agent. The physicochemical properties of the materials, annealed at 850 °C for one hour, were characterized using powder X-ray diffraction (PXRD), energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), and vibrating-sample magnetometry (VSM) at room temperature.
