We report the resonance converse magnetoelectric (CME) effect in a bilayered composite with two different resonance modes. The composite consists of a thickness-polarized piezoelectric 0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3(PMN-PT) crystal plate and a length-magnetized magnetostrictive Tb0.3Dy0.7Fe1.92(Terfenol-D) alloy plate. A low-frequency bending mode resonance is observed in the composite in addition to a high-frequency longitudinal mode resonance. The bending and longitudinal mode resonances are found at 17.5 and 66.5 kHz, respectively, while their respective resonance CME coefficients are as large as 4.1 and 7.9 G/V, at an optimal bias magnetic field of 400 Oe. This dual-mode resonance CME effect forms a basis for dual-mode/-frequency operations of coil-free electromagnetic devices.
