摘要
Fe96-xZrxn4 （1〈x〈12） nanowires were prepared by electrodepositing into anodic aluminum oxide templates. The diameter of nanowires used is 100 nm and the aspect ratio is 75. The structure of the nanowire arrays was studied by selected area electron diffraction, X-ray diffraction and MOssbauer spectrometer. The phase structure of Fe96_xZrxB4 nanowires is changed from a crystalline phase to a homogenous amorphous phase with the increasing of Zr content. The Fe96_xZrxB4 nanowires are com- posed of a-Fe-like and Zr-rich FeZrB phases. With the increasing of Zr composition, the atoms of Fe site in both phases are more disorderly, and the ct-Fe-like phase decreasing with the FeZrB phase increasing. The anisotropy of Fe96_xZrxB4 nanowires becomes more obvious with the increasing of Zr content, and the easy magnetizing axis is parallel to the nanowire arrays.
