Abstract: Magnetoelectric (ME) effect has been studied in a device of Pb(Zr₀.₅₂Ti₀.₄₈)O₃(PZT) drum transducer, NdFeB magnet, and Fe-core solenoid. A unique ME effect is found to originate from the magnetic force-induced effectively amplified piezoelectric effect. Under the application of a magnet with dimensions of Φ22 x 7.6 mm² , a giant ME coefficient of 13.2 V/cm Oe and a power density of 16.4,μW/Oe across a 14 kΩ resistor were obtained at the first order radial resonance frequency of 650 Hz. Importantly, with increasing magnet mass, the resonance frequency decreases, while the resonance ME effect first increases and then decreases, which means a tunable resonance ME effect.
