Abstract :
The higher-order space-time Floquet harmonics resulting from the scattering of magnetostatic waves by surface acoustic waves have been investigated. Experimental results are reported on the observation of these higher-order modes in magneto-acoustic Bragg interactions in magnetic films. The results are compared to the theoretical predictions based on the coupled-mode analysis
