Using pulsed laser deposition (PLD) and post-annealing we fabricated polycrystalline yttrium iron garnet films (YIG) on silicon Si(001) substrates. A temperature of 1000 °C and an annealing time of 10 min result the films with low coercivity Hc = 14 Oe and magnetic losses ∆H = 17 Oe accompanied by effective saturation magnetization 4πMf = 1800 Gs. High quality of the YIG films synthesized on Si substrates allowed simple observation of the magnetostatic waves (MSWs) using MSW filter. MSWs spectrums cover 2-5 GHz frequency range and represent magnetostatic surface waves (MSSW) and magnetostatic forward volume waves (MSFVW) geometries. Observations were found to be in the reasonable agreement with qualitative theoretical predictions.
