“…The dependence of the magnetization easy axis on shape anisotropy and crystalline anisotropy, as previously predicted on the basis of XRD and TEM analysis, was reconfirmed. Moreover, in agreement with previous studies, a strong reduction of the coercivity was observed as the diameter increases . One can see that the coercivity decreases from about 1.80 to 0.67 kOe with an increase in the diameter from 30 to 90 nm with the applied field parallel to the nanowires.…”

Highly ordered arrays of Co nanowires with different diameters have been fabricated by electrodeposition in nanoporous anodic aluminum oxide membranes. The prepared Co nanowires have hexagonal close-packed structure and are [002] preferred oriented crystalline with the c-axis parallel to the long axis of the nanowires. The high anisotropy of Co nanowires offers the possibility to control their magnetic properties and microwave properties, which are experimentally characterized by a vibrating sample magnetometer and frequency-swept ferromagnetic resonant flip-chip based techniques, respectively. The nanowire arrays exhibit strong magnetic anisotropies. As for the ferromagnetic resonance frequency, it increases with increasing value of the applied field, and zero-field ferromagnetic resonance frequencies up to 28-34 GHz. Also, the magnetic anisotropies and high ferromagnetic resonance frequency of Co nanowire arrays, are shown to be determined by the combined effect of shape anisotropy, crystalline anisotropy, and dipolar interactions between the nanowires.

One-dimensional Fe, Co, Ni nanotube arrays ware fabricated successfully by the electrochemical deposit in porous anodic alumina oxide (AAO) templates. The microstructure of nanotubes were observed by scanning (SEM) and transmission electron microscopes (TEM) respectively. The obtained Fe, Co, Ni nanotubes are arranged orderly. The magnetic property of nanotubes was measured and analyzed. The results show that the residual magnetization of Ni nanotubes is the biggest, and that of Fe nanotubes is the smallest. It is easy to be magnetized along the axial direction.
