Co nanowire array was embedded into anodic aluminum oxide template by DC electrodeposition method. The result of X-ray diffraction (XRD) analysis shows that the prepared Co nanowire array exhibit a hexagonal close packed (hcp) structure with preferred orientation of (100) plane. A broadband ferromagnetic resonance system operating in the frequency range from 0 GHz to 50 GHz, was taken to measure the microwave ferromagnetic resonance of the Co nanowire array with a coplanar waveguide using the flip-chip technique. The results show that the Co nanowire array has a gyromagnetic ratio of 2.03×10–3GHz/Oe, a zero-filed ferromagnetic resonance frequency up to 10.8 GHz and a large effective magnetic anisotropy field of 5.3 kOe.
