Abstract: The dynamic response of nanoscale circular Permalloy antidot arrays in a square lattice geometry has been systematically investigated as a function of hole diameter using broadband ferromagnetic spectroscopy. Two main resonance modes were observed for the field applied along the lattice edge, whereas only a single main mode was observed along the diagonal of the square lattice. We also observed that the frequency of all modes can be systematically tuned by varying the antidot diameter. Our experimental results have been further validated using micromagnetic simulations. © 2011 American Institute of Physics.
