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.5 p.application/pdfengcc-by-nc-nd (c) González, 2020http://creativecommons.org/licenses/by-nc-nd/3.0/es/Ones acústiques de superfícieMagnetostriccióTreballs de fi de grauAcoustic surface wavesMagnetostrictionBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
