Magnetoelastic transports of surface acoustic waves (SAWs) in a YIG/GGG substrate were investigated. Here, efficient interaction between acoustic phonons and YIG magnons was generated with large absorption in SAW trasmission amplitude. The ultra-low magnetic loss YIG-based magnomechanical system will lead to generation of strong magnon-phonon coupling.
