Thickness effects on the ME coefficient αMEand electromechanical resonance frequency of Metglas/PZT/Metglas tri-layered laminates are investigated. The thickness of the magnetic plate is changed by assembling different numbers of the Metglas thin sheets (30 μm for each layer) while the PZT plate is maintained at constant thickness (0.5 mm). At 1 kHz of the applied alternating magnetic field, only one peak presents in the ME coefficient (αME) versus static magnetic field (HS) curve. As the thickness rationincreases, the peak value of μMEfirst increases and reaches a maximum at approximatelyn= 0.519, and then decreases afterward. The peak position (Hoptim) moves steadily toward a higher value asnincreases. It is suggested that the relaxation factorkof the magnetic phase is reduced asnincreases, causing the decrease of the piezomagnetic coefficientd11,mand the increase ofHoptim. By employing the micromechanics model and considering the degradation ofd11,mwithn, an optimized thickness ratio of 0.5 is predicted, which is in agreement with the experimental observations. The resonance frequency of the laminate increases withn, which is consistent with the calculation using a straightforward mixture law.
