Aim\ The preparation of the ordered nano porous anodic alumina films is reported. Methods\ The related parameters and the self ordering mechanism of the nano channel formed during anodization porcess have been investigated. Results\ Using the porous film as the templates, the iron nanorod array by electrochemical deposition of Fe into these nano channels have been fabricated. Conclusion\ The coercivity of the magnetic nanorod array was found to be highly anisotropic.
