Autor: E. Albisetti, D. Petti, M. Madami, S. Tacchi, P. Vavassori, E. Riedo, R. Bertacco

Publikováno v: AIP Advances, Vol 7, Iss 5, Pp 055601-055601-7 (2017)

Magnonics is envisioned to enable highly efficient data transport and processing, by exploiting propagating perturbations in the spin-texture of magnetic materials. Despite the demonstrations of a plethora of proof-of-principle devices, the efficient

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 D1 = 300 nm and D2 = 150 nm with a
