摘要: Understanding the magnetization dynamics in lattices of antidots (holes, rather than bumps) is interesting for applications spintronics and data-storage technology. Magnetic antidot have potential as magnetophotonic crystals, due to their higher spin-wave velocities (steeper dispersion), compared dot arrays. This study shows that, by tuning shapes holes (and hence anisotropy) arrays, one can control spectra engineer domain structure a thin film Co${}_{2}$Fe${}_{0.4}$Mn${}_{0.6}$Si. work should significant impact on magnetic filters, splitters, other magnonic devices.
