Understanding the correlation between magnetomechanical coupling factors () and damping factors () is a key pathway toward enhancing the magnetomechanical power conversion efficiency in laminated magnetoelectric (ME) composites by manipulating the magnetic and mechanical properties of Fe-based amorphous metals through engineering. The and factors of FeSiB amorphous ribbons annealed in air at different temperatures are investigated. It is found that and factors are affected by both magnetic and elastic properties. The magnetic and elastic properties are characterized in terms of the magnetomechanical power efficiency for low-temperature annealing. The and of FeSiB-based epoxied laminates with different stacking numbers show that a -3 dB bandwidth and Young's modulus are expressed in terms of the magnetomechanical power efficiency for high lamination stacking.
