| Abstract |
The Ni0.5Zn0.5Fe2O4 nanoparticles about 30 nm were prepared using sol-gel method with metal nitrates
dissolved in 2-methoxyathanol. The concentrations of the metal nitrates are adjusted from 0.1 to 0.75 M in
order to study the influence on the structural and magnetic properties. The structure and morphology
characterization revealed that the crystallinity was improved and the nanoparticle size was increased with the nutrition solution concentrations up to 0.5 M. Degraded crystallinity together with decreased nanoparticle size were observed for concentration of 0.75 M. The saturation magnetization at room temperature reached maximum at 0.5 M, which can be explained by considering the crystallinity and size effect.
