Structure and physical properties of iron nanotubes obtained by template synthesis

Iron nanotubes with an aspect ratio of approximately 100 are synthesized by electrochemical deposition using polyethylene terephthalate templates. The structural and morphological features of the nanotubes are studied in detail by scanning electron microscopy, energy dispersive analysis, transmission electron microscopy, electron diffraction, X-ray diffraction analysis, and gas permeability. The main magnetic parameters and their dependence on temperature are determined by vibration magnetometry and Mössbauer spectroscopy.
