Periodic nanopatterning of metallic ferromagnets allows one to create devices with artificially tailored band structures for spin waves. We discuss our recent experiments performed on two-dimensional periodic lattices of nanoholes created in thin Ni80Fe20 films which exhibit man-made allowed minibands and forbidden frequency gaps provoking artificial crystal behavior and metamaterials properties.
