Abstract: Nanocrystalline zinc ferrite(ZnFe2O4)was synthesized at room temperature(about 25) by mechanochemical reaction of Fe2O3and ZnO powder under The effectof high energy ball milling.The prepared nanocryst allite was characterized by XRD, TEM, Mossbauer spect roscopy and IR spect rum.The results showed that the as milled nanocryst alline zinc ferrite is non-normal spinel structure and show superparamagnetism.There are many defects in the as milled nanocryst alline zinc ferrite.

Key words: Mechanochemical synthesis, Nanocrystallite, Zinc ferrite
