Nanospinel ferrites are the class of the magnetic materials having wide
applications in industry and are current subject of study. When compared
some other kinds of magnetic materials, spinel ferrites are easily
synthesizable at nanoscale.  The structural and magnetic properties of
these materials are dependent up on the type of metal ions, doping
concentration, synthesis technique and calcination temperature. The
magnetic properties especially in the case of spinel ferrites are
dependent up on the occupancy of metal ions in the two crystallographic
sites namely tetrahedral (A) and octahedral [B].
    In this talk, sol-gel auto-ignition technique used for nanoferrites
synthesis will be explained. Some of the results obtained on NiFeO4
doped with Al and Zn, CoAlxFe2-xO4 and CuGdxFe2-xO4 nanoferrites will
be presented.
