Abstract: | Using the solid-phase pyrolysis and chemical vapor deposition of nickel-phthalocyanine, we have fabricated ferromagnetic Ni
nanoparticles in carbon matrices. The composition, structure, morphology, and magnetic properties of samples were investigated
by means of scanning electron microscopy, energy dispersive X-ray microanalysis, X-ray diffraction technique, and ferromagnetic
resonance. It is shown that the sizes of nanoparticles can be varied from ∼10 nm to ∼500 nm depending on the temperature and
time of pyrolysis. The used method allows us to synthesize metal nanoparticles in different carbon matrices: in amorphous
carbon plates, in graphitic capsules, and in carbon nanotubes. |
