Soft magnetic oxides, MFe2 O4, where M is a divalent metallic ion, have a spinel structure and in the bulk form have many applications in telecommunication and electronics. Nano particles of these ferrites have different characteristics in comparison with the bulk ones. The use of magnetic particles to induce hyperthermia in biological tissues is an important factor for tumor therapy. Hyperthermia is a therapeutic procedure, which is used to raise the temperature of a region of the body affected by cancer to 42-46oC. This method involves the introduction of ferromagnetic particles in to tissues, and their subsequent irradiation with an alternating electromagnetic field. In this work we have prepared and characterized Mn ferrite nanopowders with a mean particle size of 5 nm. The powders were characterized by XRD method and particle size was calculated by Scherrer*s formula.
