Abstract

The effect of electrical resistance load on the magnetoelectric (ME) coupling of laminated composite of Tb0.3Dy0.7Fe1.92(Terfenol-D) magnetostrictive alloy and 0.7Pb (Mg1/3Nb2/3)O30.3PbTiO3(PMNPT) piezoelectric single crystal is investigated at both non-resonance and resonance frequencies. The results show that (i) the ME coefficient and ME resonance frequency increase with the increase in electrical resistance load, and (ii) the maximum ME power occurs in open-circuit condition. The present study provides the basis for the design of ME sensors and their signal-processing and electronic circuits.
