摘要：
Fe nanowire arrays were fabricated at lower voltage by alternating current (AC) electrodeposition into the highly ordered nanoholes of the porous alumina membrane (PAM) obtained by two-step anodization in oxalic acid. The morphology, structure and magnetic properties of Fe nanowire arrays were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM), respectively. The results indicate that Fe nanowires are about 50 nm in diameter which were accorded with the pores of the PAM, and stabilized in body-centered cubic (bcc) structure with a preferred orientation along (110). The easy magnetization axis is parallel to the axis of the Fe nanowires, while corresponding coercivity and squareness ratio value is 1674.5 Oe and 0.87, respectively.
