Abstracts

EN

A few micrometers thick nanocrystalline α-Fe layer with the mean crystallite size d_{XRD}=14 nm was deposited in low-pressure microwave plasma, using Fe(CO)_{5} vapour. Its nanocrystalline character was proved on its surface under SEM (surface was formed of deposited nanoparticles) and in its volume using TEM (deposited nanoparticles were stacked up, creating columns). No significant iron oxide phases were observed in the transmission ^{57}Fe Mössbauer spectrum measured at 5 K nor in the surface-sensitive ^{57}Fe conversion electron Mössbauer spectrum measured at 293 K.
