Using a hybrid device composed of a piezoelectric, GaAs, and a ferromagnetic Heusler alloy thin film, Fe3Si, we are able to quantify the amplitude of magnetoacoustic waves generated with SAWs via magnetic imaging in an x-ray photoelectron microscope. The cubic anisotropy of the sample, together with a low damping coefficient, allows for the observation of resonant and nonresonant magnetoelastic coupling. Additionally, via micromagnetic simulation, we verify the experimental behavior and quantify the magnetoelastic shear strain component in Fe3Si, which appears to be large (b2=10±4MJm−3).9 p.application/pdfeng(c) American Physical Society, 2023Ones acústiques de superfícieTransductorsMagnetostriccióAcoustic surface wavesTransducersMagnetostrictioninfo:eu-repo/semantics/article7398442024-02-01info:eu-repo/semantics/openAccess
