Abstract
Experimental results on investigation of magnonic crystals arising at surface acoustic wave (SAW) propagation in yttrium iron garnet as an artificial structure for surface magnetostatic waves propagation are presented. Tuning of magnonic gap frequency and gap depth were obtained by changing frequency and intensity of SAW that was explained in the frame of inelastic scattering of magnetostatic waves by SAW. Such tuning was shown can compensate drift of parameters due to possible change of temperature when using magnonic crystals as very sensitive magnetic field sensors. Suggested magnonic crystals are promising also for signal processing in GHz range.
