Magnetic Force Microscopy of Iron and Nickel Nanowires Fabricated by the Matrix Synthesis Technique

详细

Iron and nickel nanowires are grown by the matrix synthesis technique in the pores of the track membrane fabricated based on polyethylene terephthalate (PET). Scanning electron microscopy (SEM) and atomic force microscopy (AFM) are used to image the pores on the surface of the specimens and determine the 3d metal nanowires in a polymer bulk. The magnetization curves of the arrays of the nanowires are obtained. Magnetic properties of the nanowires are studied by the magnetic force microscopy (MFM) methods. The influence of the interposition and magnetostatic interaction of the nanowires of the magnetic metals in the polymer membrane, as well as the magnitudes and orientation of the applied external magnetic field, on the obtained MFM images is shown. The simulation results of the MFM images are in good agreement with the experimental data.
