| Abstract: | In this paper we go in depth in the study of the propagation of surface acoustic waves (SAWs) and its coupling with magnetoelastic materials (nickel, in our case). We found that the transmission coefficient of SAWs, propagating in a piezoelectric-magnetoelastic hybrid device, depends on the magnetic field and that there is a similarity with the classic ferromagnetic resonance (FMR).We also observed that there is a delay of 0.25m/s of the SAW's velocity due to the absorption from the magnetoelastic material. |
