Novelty, preparation, characterization and enhancement of magnetic properties of Mn nanoferrites using safety binder (egg white)

Nanocrystalline MnFe₂O₄ ferrite was prepared by using autocombustion technique (flash). The microstructure and magnetic properties are studied. The results of XRD and TEM clarified that, this ferrite is nanosized with particle size (39 nm). Magnetic measurements showed a ferromagnetic behavior with T_C = 613 K, the saturation magnetization M_s = 13.71 emu/g, remanent magnetization M_r = 0.1694 emu/g and, coercivity H_c = 25.6 Oe. Natural material, egg white used as an aqueous medium to extend prepare nanoparticles better than other chemical interesting materials.
