【 摘 要 】

Synthesis of Zn0.6Ni0.2Cu0.2Fe2O4 has been successfully using the co-precipitation method at a calcination temperatures of 300 °C, 400 °C and 500 °C. Thermal properties, microstructures, and magnetic properties were obtained from the characterization of Thermogravimetric Analysis/Differential Scanning Calorimetry (TGA/DSC), X-ray Diffraction (XRD), Field Emission - Scanning Electron Microscope (FE-SEM). Vibrating Sample Magnetometer (VSM) used for analyses magnetic properties of ZnCuNi Ferrite. TGA/DSC results that the reduction of weight is 6.72% in range at 95 °C–100 °C and endotermic process occurs at temperatures below 100 °C. XRD results that confirmed that the higher calcination temperature that affects the growth of ZnNiCu spinel ferrite crystals and the increase in the crystallite size are found within 17.75–20.15 nm. FE-SEM conducted that effect increase calcination temperature reduced particle size, faster diffusion of metal oxidation, and increasing the rate at which the cubic particles crystallize in spinel ferrite. The optimum conditions properties obtained for Zn0.6Ni0.2Cu0.2Fe2O4 at a calcination temperature of 500 °C, Ms = 31.79 emu/g, Mr = 12.06 emu/g, Hc = 331.06 Oe, respectively.
