ScholarBank@NUS Repository. https://doi.org/10.1021/nl060026+ | Abstract: | Brillouin measurements have been made of the spin dynamics of high-density two-dimensional hexagonally ordered 20 nm diameter Fe48Co 52 nanowire arrays, with various interwire spacings, as a function of longitudinal magnetic field. The experimental data are analyzed within the Arias-Mills theory based on interwire dipolar couplings in the arrays. The results provide conclusive evidence of collective spin waves arising from the dipolar coupling which is manifested as a reduction in spin wave frequency with decreasing interwire spacing. © 2006 American Chemical Society. | Source Title: | Nano Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/96014 | ISSN: | 15306984 | DOI: | 10.1021/nl060026+ |
