    Abstract
    We have developed Metglas/Pb(Mg(1/3)Nb(2/3))O(3)-PbTiO(3) magnetoelectric (ME) laminates that have notably larger ME coefficients, with maximum values of up to 45 V/cm Oe. Based on this giant ME effect, the dc magnetic field sensitivity for Metglas/PMN-PT laminate sensors was improved by a factor of > 3, relative to that for Metglas/Pb(Zr,Ti)O(3) (PZT)-based ones of the same geometry. Our new ME sensor can detect dc magnetic field changes as small as (i) 5 nT at 1 kHz and (ii) 1 nT near the resonant frequency in a shield chamber. (C) 2011 American Institute of Physics.
