“…When the applied field is parallel to the nanowire's axis, hcp Co nanowire arrays have a coercivity of 520 Oe in our experiments. This result is almost the same as the reported values of the coercivity for hcp Co nanowires with the caxis perpendicular to the nanowire's axis [8,10,25], and lower than the reported values of the coercivity for hcp Co nanowires with the c-axis parallel to the nanowire's axis [10,26,27]. Some works [8,9,27] have reported that the effective anisotropy of the magnetic nanowire arrays comes from the competition between the magnetocrystalline anisotropy and the shape anisotropy.…”

“…Nanowire magnetization process is generally in three areas by the following factors [17,18]: magnetocrystalline anisotropy, shape anisotropy, and the interaction between the nanowires. Some works [19,20] have reported that the effective anisotropy of the magnetic nanowire arrays comes from the competition between the magnetocrystalline anisotropy and the shape anisotropy.…”

The Co nanowires with different diameters were prepared by pulsed electrodeposition into anodic alumina membranes oxide templates. The micrographs and crystal structures of nanowires were studied by FE-SEM, TEM, and XRD. Due to their cylindrical shape, the nanowires exhibit perpendicular anisotropy. The coercivity and loop squareness (Mr/Ms) of Co nanowires depend strongly on the diameter. Both coercivity and Mr/Ms decrease with increasing wire diameter. The behavior of the nanowires is explained briefly in terms of localized magnetization reversal.

“…Moreover, iron exhibits low cubic magnetocrystaline anisotropy, allowing improvement of the magnetic anisotropy to be obtained by means of the selection of optimum material geometry. The total anisotropy represents the competition among magnetocrystaline, shape and magnetoelastic anisotropies and dipolar interaction [18]. Magnetoelastic anisotropy, originating from external stress on the ferromagnetic material, may also affect the direction of the favored magnetization.…”

The iron nanowire arrays (NWs) were fabricated by DC electrodeposition into hexagonally ordered alumina pores. With the use of X-ray diffraction analysis, the structure of iron wires was determined. The iron wires have the Body Centered Cubic structure. The influence of cathodic deposition potential and parameters of membrane on the magnetic properties of nanowire arrays was investigated. Magnetic properties analyzed by VSM measurements suggest that the easy axis of magnetization follows the nanowire axis, with coercivity increasing with a decrease of nanowire diameter and length. The dependence of the height of Fe wires on the electrodeposition potential was determined. The low cathodic potential and smaller pore diameter are the synthesis parameters most beneficial for large coercivity with easy axis along nanowires.
