Three resonance modes, a first-order bending resonance mode and nonlinear and first-order longitudinal resonance modes, were observed in Terfenol-D/lead zirconate titanate(PZT)/Ni asymmetric magnetoelectric(ME) laminated composites. The ME outputs and resonance modes were tuned by the ratio of the thickness of the Ni negative magnetostrictive layer to the Terfenol-D positive magnetostrictive layer that of the( t Ni / t T ). As ( t Ni / t T ) increased from 0.4 to 2.0, the strength of the first-order longitudinal resonance mode was decreased, while the first-order bending resonance was enhanced. The asymmetric threelayered composites exhibited a large ME coefficient of 250mV/(cm Oe) under a bias magnetic field of 400 Oe at quasi-static frequency (1 kHz). This work sheds some light on the design of ME composites with tunable ME resonance modes and multifrequency operation.
