Abstract

Co0.4Ni0.5Zn0.1Fe2O4 magnetic nanoparticles have been succesfully synthesized by using the co-precipitation method with the various synthesis temperature (50, 70, 90, 110, and 130 Celcius degree) and constant concentration of NaOH. Characterization test of Co0.4Ni0.5Zn0.1Fe2O4 magnetic nanoparticles was conducted by X-Ray Diffraction (XRD) and Transmission Electron Microscopy (TEM) to analyze particle size, crystal structure, and the morphology. From the results of XRD analysis, the diffraction pattern showed that Co0.4Ni0.5Zn0.1Fe2O4 magnetic nanoparticles had a spinel cubic crystal structure. Beside of that, the crystanility increased with the increase of synthesis temperature. The lattice parameters of Co0.4Ni0.5Zn0.1Fe2O4 magnetic nanoparticles in temperature 90 Celcius degree was 8.270 Angstrom, and there was no significant change in the lattice parameters for the all samples. Investigated by TEM, the grain size of Co0.4Ni0.5Zn0.1Fe2O4 magnetic nanoparticles at temperature 90 Celcius degree was 15.32 nm. In addition, FTIR (Fourier Transform Infra Red) characterization was conducted to determine the vibration mode of Co0.4Ni0.5Zn0.1Fe2O4 magnetic nanoparticles. The result of vibration bands in Co0.4Ni0.5Zn0.1Fe2O4 magnetic nanoparticles was the absorption peak of the octahedral site was placed at the 465.5 cm-1 , while the absorption of the tetahedral site was placed at 674.2 cm-1
