  • Abstract
    Heat treatment was applied to Mn nanoparticles to introduce Mn3O4 nanocrystals into the sample. X-ray diffraction spectra and the temperature dependence of the magnetization and coercivity of the Mn nanoparticles were studied. A large coercivity was observed in manganese nanocomposites containing Mn3O4 crystals. This coercivity, which was found to decrease almost linearly with increasing temperature, is mainly due to the small crystallite size of the ferrimagnetic Mn3O4.
