The converse magnetoelectric (CME) effect was investigated theoretically and experimentally for multi-push-pull mode Metglas/Pb(Zr,Ti)O-3/Metglas laminates. The experimental and theoretical values of the CME coefficient (alpha(B)) exhibited similar trends. A large alpha(B) = 6.94 G/V was observed at 1 kHz under a dc magnetic bias of 11 Oe. At an electromechanical resonance frequency of 29.6 kHz, the laminate exhibited a giant value of alpha(B) = 79.5 G/V. These results show significantly enhanced CME effects in multi-push-pull mode laminates, compared to previously reported ones with different structures and materials.
