摘要：

Two series samples of Iron Oxide nanoparticles doped with nickel and cobalt with different doping values (x = 0.01; 0.03; 0.05 and 0.07), were successfully synthesized by using sol-gel method, and then they were characterized by X-ray diffraction, scanning electron and vibrating sample magnetometer (VSM). X-ray diffraction analysis of two series samples showed the formation alpha-Fe2O3 nanoparticles, accompanied by two phases iron spinels, CoFe2O4 and NiFe2O4. In addition, the variations in grain size were observed for both two series. The observation by scanning electron microscopy reveals a change in the morphology of the grains of all the samples doped, which confirm the cobalt and nickel effect on the morphology of iron oxide nanoparticles. Magnetic measurements which were measured by VSM showed significant magnetic parameters such as coercivity and magnetization besides the ferromagnetic behavior of both two series doped with Cobalt and Nickel.
