Title: | Dual-resonance converse magnetoelectric and voltage step-up effects in laminated composite of long-type 0.71Pb(Mg₁/₃Nb₂/₃)O₃-0.29PbTiO₃piezoelectric single-crystal transformer and Tb₀.₃Dy₀.₇Fe₁.₉₂magnetostrictive alloy bars | Authors: | Leung, CM Or, DSW Wang, F Ho, SL |
Issue Date: | 15-May-2011 | Source: | Journal of applied physics, 15 May 2011, v. 109, no. 10, 104103, p. 1-6 | Abstract: | We report a dual-resonance converse magnetoelectric effect and a dual-resonance voltage step-up effect in a laminated composite made by sandwiching the output (or secondary) section of a long-type 0.71Pb(Mg₁/₃Nb₂/₃)O₃-0.29PbTiO₃(PMN–PT) piezoelectric single-crystal transformer having a longitudinal-longitudinal polarization between two Tb₀.₃Dy0₀.7Fe₁.₉₂ (Terfenol-D) magnetostrictive alloy bars having a longitudinal magnetization. The report ed converse magnetoelectric effect originates from the mechanically mediated resonance converse piezoelectric effect in the PMN–PT transformer and resonance converse magnetostrictive effect in the Terfenol-D bars. The additional voltage step-up effect results from the mechanically mediated resonance converse and direct piezoelectric effects in the PMN–PT transformer. The composite shows two sharp resonance peaks of 0.39 and 0.54 G/V in converse magnetoelectric coefficient (αᵦ=dB/dV[sub in]) and of 1.4 and 2.1 in voltage step-up ratio (V[sub out]/V[sub in]) at about 54 and 120 kHz, corresponding to the half- and full-wavelength longitudinal mode resonances, respectively. The measured magnetic induction (B)exhibits good linear relationships to the applied ac voltage (V[sub in]) with amplitude varying from 10 to 100 V in both resonance and nonresonance conditions. These dual-resonance effects make the composite great promise for coil-free electromagnetic device applications. | Keywords: | Bars Dysprosium alloys Electromagnetic induction Iron alloys Laminates Lead compounds Magnesium compounds Magnetisation Magnetoelectric effects Magnetostriction Piezoelectric materials Piezoelectricity Terbium alloys |
