Nickel-zinc ferrite Ni0.35Zn0.65Fe2O4 powers are synthesized by sol-gel auto-combustion synthesis method, The effects of ignition temperature on ferrite products character were investigated. The structure and magnetic property are studied using XRD and VSM. The results show that spinel nickel-zinc ferrite powders can be successfully prepared in the conditions of ignition temperature 400℃, the size of powder particles is approximately 20nm, the saturation magnetization is up to ７０．２ A•m2/kg, which means that spinel nickel-zinc ferrite powders can be prepare directly by Sol-gel auto-combustion method .
