摘要

The arrays of Ni nanotubes have been synthesized in pores of polyethylene terephthalate membranes by electrochemical method. Morphological and structural characteristics were studied by scanning electron microscopy, gas permeability, energy-dispersive X-ray spectroscopy and X-ray diffraction analysis. It was shown that Ni nanotubes have lateral dimensions corresponding to the membranes pores parameters (length ~12 μm and pores diameters 400 nm) with the tubes walls thickness in the range from 60 nm to 160 nm, depending on the deposition conditions. Ni nanotubes have the face-centered cubic lattice phase. The dependence of crystal structure parameters on temperature and voltage of synthesis was established. Dependences of main magnetic parameters (coercivity value and magnetization of saturation and squatness) on deposition parameters were studied. Significant magnetic anisotropy was found, but any evident influence of deposition parameters on magnetic properties was not found.
