The mixture of metal and diamond nanoparticles was just annealed at 1700°C in vacuum. The annealed samples were studied by high-resolution transmission electron microscopy, selected-area electron diffraction and X-ray diffraction. These analyses revealed that magnetic-metal particles are coated with uniform graphitic layers several nanometers in thickness 关键词: cobalt;electron diffraction;iron;nanostructured materials;nickel;transmission electron microscopy;X-ray diffraction;thin graphitic coating;magnetic-metal nanoparticles;diamond nanoparticles;Co;Ni;Fe;high-resolution transmission electron microscopy;selected-area electron diffraction;X-ray diffraction;magnetic-metal particles;uniform graphitic layers;1700 C;C
