Yttrium-iron garnet (YIG) film was deposited by ion-beam sputtering on gadolinium gallium garnet (GGG) substrate with the periodical array of grooves ion-etched in its surface. Spin-wave excitations in the fabricated structure were studied by the ferromagnetic resonance (FMR) method and by the spin-wave spectroscopy. Results were compared with ones for the YIG film deposited on GGG substrate without the periodical relief.
