Notes:
A sol-gel process was used to synthesize nanosized Ca-Zn ferrite powders. DTA-TG, XRD andSEM techniques are employed to investigate the thermal decomposition of the dry gel, phase compositionand microstructure of nanosized ferrite particles. The results revealed that the Ca0.4Zn0.6Fe2O4 phaseappeared while calcined the gel powders at 300 °C for 2 hrs, and the Ca0.4Zn0.6Fe2O4 crystalline can beformed completely at 400 °C. Hysteresis loop indicated that the nanocrystallites size has great influenceon the magnetic properties, which leads to the increase of the specific saturation magnetization and thedecrease in coercivity of the samples with increasing the particle size
