dcterms.abstract | We report an enhanced magnetoelectric (ME) effect in a heterostructure consisting of a long-type, longitudinally–longitudinally polarized 0.71Pb(Mg₁/₃Nb₂/₃)O₃–0.29PbTiO₃ (PMN-PT) piezoelectric single-crystal transformer with its input part sandwiched between two longitudinally magnetized Tb₀.₃Dy₀.₇Fe₁.₉₂ (Terfenol-D) magnetostrictive alloy bars. The observed ME effect has two independent operational modes: namely, ME sensing mode and ME transduction mode. The ME sensing mode features a large ME voltage coefficient (αV) of ∼0.32 V/Oe over a flat frequency range of 1–50 kHz, while the ME transduction mode possesses two colossal resonance αV of 7.6 and 7.9 V/Oe, corresponding to the first and second longitudinal resonances, at 56.2 and 127.9 kHz, respectively. This enhanced dual-mode ME effect not only enables the application potential of the heterostructure, but also advances the technology of power-free ME sensors and transducers. | - |
