ScholarBank@NUS Repository. https://doi.org/10.1109/TMAG.2013.2240659 | Abstract: | The dispersion of spin waves in a Permalloy binary antidot array constituted by two alternated antidot sublattices with different diameters of the circular holes has been investigated. The diameters of the holes are D 1=300 nm and D2=150 nm with a holes center-to-center spacing of 425 nm. The spin wave frequency has been measured with Brillouin light scattering applying a magnetic field along the edge of the square unit cell of the lattice and sweeping the spin-wave wave vector along the perpendicular direction. The measured dispersion has been compared with calculations performed by the plane wave method, achieving a good agreement with the experimental results over the whole wave vector range. © 2013 IEEE. | Source Title: | IEEE Transactions on Magnetics | URI: | http://scholarbank.nus.edu.sg/handle/10635/83055 | ISSN: | 00189464 | DOI: | 10.1109/TMAG.2013.2240659 |
