ScholarBank@NUS Repository. https://doi.org/10.1063/1.4705301 | Abstract: | We report on the experimental observation of dual magnonic and phononic bandgaps in bi-component nanostructured crystals. The dispersion relations of linear periodic arrays of alternating Fe (or Ni) and Ni 80Fe 20 nanostripes on a SiO 2/Si substrate, mapped by Brillouin spectroscopy, feature distinct bandgaps. Calculations of the magnon and phonon dispersions yield good agreement with experiments. No magnon-phonon interaction is detected for the modes observed, making the structures studied a potential platform for the separate and simultaneous processing of information carried by hypersonic magnons and phonons, with no undesirable cross-talk between them. © 2012 American Institute of Physics. | Source Title: | Applied Physics Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/82794 | ISSN: | 00036951 | DOI: | 10.1063/1.4705301 |
