Аннотация: Structure and magnetic properties of Co nanoparticles in the high-porous amorphous carbon matrix are presented. The average size of cobalt particles is 20 nm. The Co nanoparticles are ferromagnetic and characterized by the local magnetic anisotropy fields H-a = 10 kOe. The material consists of fcc and hcp Co phases and highly defecПоказать полностьюtive phase with high concentration of stacking faults. There are no variations observed in the line shape of the NMR spectrum of Co particles at different temperatures. This implies that there are no polymorphous transformations inside Co particles with temperature.
