Abstract
In this paper, a magnetoelectric laminate composite based on length magnetized Metglas and length-polarized ternary 0.35Pb(In1/2Nb1/2)O3-0.35Pb(Mg1/3Nb2/3)O3-0.30PbTiO3 (PIMNT) single crystal has been presented. This Metglas/PIMNT L-L mode composite exhibits ultrahigh magnetoelectric voltage coefficients of â¼17Â V/Oe at quasi-static frequency and of â¼147Â 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 8.6Â pT/Hz1/2@1Â Hz. Due to its giant magnetoelectric voltage coefficients, the maximum magnetic-field-energy-harvesting output power reaches 29.2Â mW/Oe2, 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.
