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.
