Abstract: | Taking advantage of the magnetoelastic effect to modify magnetic states of ferromagnets, is becoming a trending alternative to the more traditional procedure of just applying an external magnetic field. In this paper, we study the dynamic magnetoelastic effect using surface acoustic waves as a function of the different magnetic states in a hybrid device made of a piezoelectric substrate and a Nickel thin film. Our data shows that the absorption of the acoustic waves changes with the applied magnetic field. We identify resonance peaks that vary with the acoustic wave frequency, and we compare it with a conventional ferromagnetic resonance technique. |
