    • Abstract

       

      Polycrystalline samples of MnxFe3−xO4 (0⩽x⩽1) have been prepared following a novel route involving a reaction of desired quantities of stabilized MnO and FeO with Fe2O3 at high temperatures. The novel route of preparation of pure MnxFe3−xO4 precludes the presence of Mn3+ and Fe2+ ions. These samples have been characterized for their structural and magnetic properties using x-ray diffraction, Fe57 Mössbauer spectroscopy and bulk magnetic measurements such as initial permeability, loss factor, remanence and coercivity. All our experimental data clearly show the formation of single cubic phase over the entire range of composition. The degree of inversion in these systems decreases with increasing manganese concentration.
