In this paper, we present the structural and magnetic properties of Co0.7Ni0.3Fe2O4 nanoparticles. The nanoparticles are prepared by the sol-gel method; structural analysis by X-ray diffraction shows that the nanoparticles are pure phase with the spinel structure. Transmission electron microscopy analysis reveals the local microstructure of the particles and their size range of 6-8 nm, with isometric shape. The magnetic properties obtained with magnetic properties measurement system demonstrate the soft magnetic character of the nanoparticles.
