АннотацияNi-C nanoparticles powder (NP) was synthesized using high-temperature pyrolysis of nickel nitrate in an organic solvent. The NP was characterized by transmission electron microscopy (TEM), energy dispersive x-ray spectroscopy (EDXS) and selected-area electron diffraction (SAED). Structural characterization of the samples confirmed the formation of small, medium and large Ni nanoparticles with face-centered cubic structure (fcc) and enlarged lattice parameter. Magnetic circular dichroism (MCD) of samples with different mean particle sizes showed a red shift with decrease of mean particle size
