Ultrahigh magnetoelectric voltage coefficients in laminates of Metglas and length-polarized ternary 0.35Pb(In(1/2)Nb(1/)2)O-3-0.35Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3) single crystals

摘要

In this paper, a magnetoelectric laminate composite based on length magnetized Metglas and lengthpolarized ternary 0.35Pb(In(1/2)Nb(1/)2)O-3-0.35Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3) (PIMNT) single crystal has been presented. This Metglas/PIMNT L-L mode composite exhibits ultrahigh magnetoelectric voltage coefficients of similar to 17 V/Oe at quasi-static frequency and of similar to 147 V/Oe at resonance frequency, which are much larger than other magnetoelectric composites reported so far. Analysis of magnetic field sensitivity indicates that the estimated noise equivalent magnetic induction of the proposed composite is as low as 8.6 pT/Hz(1/2)@1 Hz. Due to its giant magnetoelectric voltage coefficients, the maximum magnetic-fieldenergy-harvesting output power reaches 29.2 mW/Oe(2), which is about 3.65 times than that of previously reported Metglas/PMNT multi-push-pull mode composite. Accordingly, the proposed Metglas/PIMNT L-L mode composite shows promising applications in magnetic field detection sensors as well as transducers for magnetic field energy harvesting.
