Abstract

Changes in the morphology of FeNi alloy nanowires during annealing at different temperatures were studied by transmission electron microscopy. In this work, kinds of morphologies including composite oxide wire/tube, wire@tube (or core-shell) and pure tubular microstructures were obtained successfully. The structure can be tuned by changing the annealing temperature. The formation mechanism was discussed in detail based on ion diffusion and Kirkendal effect. The as-prepared and annealed samples were characterized by the X-ray diffraction (XRD), transmission electron microscopy (TEM) and EDS mapping, respectively. The material composition of the nanostructures with different morphologies was further determined, and the cation diffusion mechanism was deduced. The result of magnetic measurement showed the coercivity and squareness of the nanostructures perpendicular to the AAO film surface decrease with the increase of annealing temperature, and the hysteresis loop of the sample annealed at high temperature is in a wasp-waist shape, which is consistent with the result that the sample contains multiple magnetic phases. Obviously, the present ferrite heterogeneous composite microstructures have potential application as a multifunctional magnetic material.
