I. V. Kasi Viswanath, Y. L. N. Murthy, Kondala Rao Tata and Rajendra Singh

Nano size nickel ferrite, copper ferrite, zinc ferrite, nickel copper ferrite, nickel zinc ferrite and nickel copper zinc ferrite powders have been prepared by citrate gel precursor method and calicinated at 800oC temperature. The resulting powders were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The ferrite powders showed XRD line broadening and sizes of the crystals were calculated 20-65 nm at 800oC temperature. Comparing the size of ferrites by addition of transition metal were discussed.
