The application of dynamic magnonic crystals, created by a surface acoustic wave, to measure the parameters of surface magnetostatic waves in YIG - GGG structures is considered. The methods and results of measuring the dispersion characteristics of surface magnetostatic spin waves (SMSW) at different angles between the magnetic field direction and the wave vector in the YIG film plane are described. The method is based on measurements of reflected SMSWs at frequencies of forbidden magnonic gaps, using the same antenna for exciting incident waves and registrations of reflected ones. Measurements of the frequency width of these reflected SMSW permit to determine its attenuation parameter. The results of measurements of the dispersion curves at several angles between the magnetic field direction and the wave vector in the YIG film plane are presented as well as the measurement results on attenuation parameters.
