Abstract: A complex investigation of the morphology, sizes and composition of carbon nanoparticles doped wit- iron atom clusters in the carbon nanopowders synthesized on the surface of iron plate (substrate) was performe: using SEM, EDX and AES. It was shown that the magnetic carbon nanopowder, synthesized at 700°C by the combination of ethanol vapor pyrolysis and chemical-vapor deposition (CVD) in the free-poured state, represent a nanocomposite, which is a mixture of carbon spherical nanoparticles (NP) with the average diameter of ~200nm ar._ carbon nanotubes (NT) having the diameter of <200nm and the lengths of The carbon nanoparticles have a structure of core-shell type spheres with the core of pure iron atom clusters, while in carbon nanotubes the iron aicx clusters are mainly concentrated at one end of nanotubes, exactly at the tube channel inlet. The iron concentration in carbon nanopowder of such composition is equal to 2.1 at%
