Co0.4Ni0.5Zn0.1Fe2O4 nanoparticles were synthesized by using the co-precipitation method with the various synthesis temperature (50, 70, 90, 110, and 130 °C) and constant concentration of NaOH (3 M). Characterization of Co0.4Ni0.5Zn0.1Fe2O4 magnetic nanoparticles was conducted by XRD and TEM to analyze particle size, crystal structure, and the morphology. In addition, FTIR characterization was carried out to determine the vibration mode of Co0.4Ni0.5Zn0.1Fe2O4 magnetic nanoparticles. The diffraction pattern showed that Co0.4Ni0.5Zn0.1Fe2O4 nanoparticles had a spinel cubic crystal structure. Moreover, XRD analysis showed that the crystallinity improved by adding the synthesis temperature. The lattice parameters at temperature of 90 °C was 8.270 Å, and there was no drastic difference compared to other samples. Based on TEM characterization, the grain size of Co0.4Ni0.5Zn0.1Fe2O4 nanoparticles at temperature 90°C was 15.32 nm. Meanwhile the absorption peak of the octahedral and tetrahedral sites in Co0.4Ni0.5Zn0.1Fe2O4 nanoparticles were at the 465.5 cm-1 and 674.2 cm-1, respectively. © 2024 Author(s).
