Single Metallic Nanowire Arrays (Ni, Au and Cu etc) and superlattice nanowire arrays (Ni/Au, Ni/Cu) were synthesized through template-directed electrochemical deposition method. The dual-bath technique was employed in fabrication of superlattice nanowire arrays. Anodized alumina membrane (AAM) and Ion Track-etched Polycarbonate Membrane was used as the fabrication templates. The specific electrode making technique and electrochemical deposition procedures were described in detail. Scanning electron microscope (SEM) performed all sample characterization. Vibrating sample magnetometer (VSM) and ferromagnetic resonance (FMR) were utilized to investigate the magnetic properties of single Ni nanowire arrays of different lengths and Ni/Cu superlattice nanowire arrays. The VSM data exhibited that the magnetic easy axis of samples is parallel to the nanowire axis direction and the nanowire arrays have obvious shape anisotropy. The FMR spectra indicated that the resonant field value is angular and aspect ratio dependence.
