N2 - Ferrite is an important ceramic material with magnetic properties that are useful in many types of electronic devices. In this study, structure and magnetic properties of nanostructured nickel zinc ferrite and magnesium copper zinc ferrite prepared by water-in-oil microemulsion were compared. Both ferrites samples demonstrated similar weight loss characteristics in TGA. The magnesium copper zinc ferrite showed a crystalline structure with an average crystallite size of 13. 5 nm. However, nickel zinc ferrite showed an amorphous phase. Transmission electron micrographs showed agglomerated nanoparticles with an average crystallite size of 26. 6 nm for magnesium copper zinc ferrite and 22. 7 nm for nickel zinc ferrite. Magnesium copper zinc ferrite exhibited soft ferromagnetic bahaviour whereas nickel zinc ferrite showed superparamagnetic nature.
