ScholarBank@NUS Repository. | 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. | Source Title: | Physical Review Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/98000 | ISSN: | 00319007 |
