Ordered CoFe(2)O(4) nanowire arrays with preferred crystal orientation and magnetic anisotropy
CoFe(2)O(4) nanowire arrays were fabricated by electrodeposition of Fe(2+) and Co(2+) into anodic aluminum oxide (AAO) templates and further oxidization. The phase structure of the nanowires is cubic spinel-type, and the XRD result exhibits perfect preferred crystallite orientation along the nanowir...

Summary: | CoFe(2)O(4) nanowire arrays were fabricated by electrodeposition of Fe(2+) and Co(2+) into anodic aluminum oxide (AAO) templates and further oxidization. The phase structure of the nanowires is cubic spinel-type, and the XRD result exhibits perfect preferred crystallite orientation along the nanowire axes. Compared with CoFe(2)O(4) nanowire arrays synthesized by other methods, the magnetic hysteresis loops demonstrate that the arrays of nanowires exhibit uniaxial magnetic anisotropy with easy magnetization direction along the nanowire axes owing to the large shape anisotropy. This approach provides a facile technology to fabricate oxide nanowires with uniaxial magnetic anisotropy. |
