Abstract Carbon nanotubes filled with iron oxides can be a promising material for medicine. In this paper, carbon nanotubes containing iron oxides were synthesized by chemical vapor deposition method. Cubic and tetragonal modifications of maghemite Fe2O3 were found inside the nanotubes along with α- and γ-phases of iron and iron carbides by electron microscopy studies. Twins were identified in the tetragonal maghemite with the {103} twinning plane.
