Abstract

The acousto-magnetic attenuation of surface acoustic waves (SAW) in an Co 60 Fe 20 B 20 exchange spring magnet is evidenced experimentally. By high-resolution magnetic imaging using photo-excitation electron microscopy (XPEEM) and magnetometry measurements, the deflection of the ferromagnet from its equilibrium state is visualized. Along a harmonic oscillator model with damping term, the experimental observation of SAW attenuation is attributed to low-frequency spin wave generation in a magnetic exchange spring. Measuring the SAW attenuation at four eigenfrequencies generated via on-chip higher-harmonic generation, we obtain a sub-GHz resonance at f0 = 538 MHz.
