In the present work we prepared NCCFO thin films by metallo-organic decomposition (MOD) technique and studied the effect of different annealing temperature on structural and magnetic properties. The prepared thin film samples are annealed at four different temperatures (550 degrees C, 650 degrees C, 750 degrees C, 850 degrees C) for two hours. The XRD results confirmed the cubic spinel structure at different temperature with the sharpening of (311) peaks. The crystallite size was found to increase with annealing temperature and was further confirmed from AFM images. All samples show distinct hysteresis curves and improved ferromagnetic properties. The saturation magnetization increases with increase in annealing temperatures, while coercivity shows anomalous behavior which could be due to transformation from single to multi domain system. The ferrite thin films with distinct magnetic properties can find applications in many technological advanced nano devices.
