| Abstract: | This work presents the study of a thin film of yttrium iron garnet (YIG) deposited on a gadolinium gallium garnet (GGG) substrate using ferromagnetic resonance (FMR) measurements, with the aim of analyze the magnon-phonon coupling under resonant conditions. Based on the study of the absorbed energy S21, as a function of frequency and magnetic field, a periodic structure following the FMR resonance profile has been observed. The analysis reveals that the periodicity is consistent with a stationary phonon mode in the GGG substrate. Finally, the magnetic properties of the sample have been determined. |
