We experimentally and theoretically report a giant magnetoelectric (ME) effect in a heterostructure made by clamping a bar-shaped magnetostrictive Tb0.3Dy0.7Fe1.92 (Terfenol-D) alloy actuator and a cymbal-type piezoelectric 0.7Pb(Mg1/3Nb2/3)O3–0.3PbTiO3(PMN–PT) (PMN-PT) single crystal-brass alloy transducer in a brass alloy frame. The reported ME effect originates from the stress-mediated product of the magnetostrictive effect in the Terfenol-D bar actuator and the mechanically transformed/amplified piezoelectric effect in the PMN PT-brass cymbal transducer under mechanically clamped conditions. The heterostructure exhibits a giant ME voltage coefficient (αV) of 440 mV/Oe at an optimal magnetic bias field of 400 Oe besides showing good linearity between the induced ME voltage and the applied ac magnetic field in the field range of 10-3–10 Oe. This αV is larger than that of conventional Terfenol-D/PMN-PT laminated composites.
