Abstract: The dynamic properties of uniform two-dimensional arrays of nickel nanowires were investigated by inelastic light scattering. Hexagonally ordered porous Al2O3 templates were fabricated on Al substrates using a two-step electrochemical anodization. Scanning electron micrographs of nanowires showed that they had a length of about 1 μm and a periodic wire spacing of 100 nm. The saturation magnetization was examined using superconducting quantum interference device magnetometry. Results exhibited strong mode quantization effects and indications of a subtle magnetic interplay between nanowires.
