Graphical abstract: The peak intensity for the product calcined at 500 °C is relatively weak, but it gradually increases with increasing the temperature. This implies that the temperature up to 700 °C leads to well crystallization of the spinel type of Ni{sub 0.45}Cu{sub 0.05}Zn{sub 0.5}Fe{sub 2}O{sub 4} phase. - Highlights: • NiCuZn-ferrite powders were obtained at a low temperature by mechanochemical activation. • The effects of the mechanical and thermal treatments on the mixtures were analyzed. • The mechanochemical method benefited achieving the lower M{sub s} and μ{sub i}. - Abstract: NiCuZn-ferrite powders were synthesized by mechanochemical treatments using NiCO{sub 3}⋅2Ni(OH){sub 2}⋅4H{sub 2}O, CuO, ZnO and Fe{sub 2}O{sub 3} as raw materials. Scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and vibrating sample magnetometer (VSM) were employed to evaluate the morphologies and structures of samples. The results indicated that the mechanochemical treatment produced several structural and chemical effects on reactants of the powder mixtures, and single phase Ni{sub 0.45}Cu{sub 0.05}Zn{sub 0.5}Fe{sub 2}O{sub 4} could be obtained after annealed at 700 °C for 2 h. In comparison with the traditional firing method, the mechanochemical method benefited achieving the lower M{sub s} and μ{sub i}, which indicated that the sample had better magnetic properties.
