Аннотация: This paper presents the results of investigations into the structure and the magnetic properties of powders consisting of Co nanoparticles in the matrix of a high-porous amorphous carbon material. An analysis of X-ray diffraction and nuclear magnetic resonance spectra revealed the presence of hcp and fcc phases of cobalt in the parПоказать полностьюticles of the powder and demonstrated the existence of a highly defective state, which could be related to a high concentration of defects of the "displaced-plane" type. The magnetometric measurements showed that the powder particles were in the ferromagnetic state and were characterized by a high field of the local magnetic anisotropy.
