%X The article presents results of investigations of hollow Fe nanotubes obtained by electrochemical deposition into the pores of polyethylene terephthalate membranes. Morphological and structural parameters of the synthesized samples of nanotubes were studied by methods of scanning electron microscopy, X-ray and energy dispersive analysis. The investigations of the magnetic properties of nanotubes were provided by Mossbauer and vibration magnetometer methods. Macro- and micromagnetic parameters of nanotubes were determined. X-ray analysis showed that walls of nanotubes have a BCC structure with non- preferred direction and the crystal lattice parameter a = 2.8627 £¿. Due to defects formation in the process of electrochemical deposition, the deformation of crystal lattices occurs at crystallites interfaces. It was also found that walls of nanotubes were formed by separate crystallites settled layer by layer. Based on the analysis of the study of dependence of the magnetization on magnetic field, it was found that the basic magnetic characteristics of arrays of Fe nanotubes decreased monotonously in the temperature range from 100 to 300 K.
