The non-linear magnetoelectric (ME) effect of Metglas/Pb(Mg1/3Nb2/3)O3–PbTiO3 heterostructures has been studied. Such effect holds promise for modulation mode ME sensor applications that require no dc bias. The non-linear ME coefficient was found to be highly dependent on the derivative of the piezomagnetic strain coefficient, which could be increased by increasing the Metglas length due to magnetic flux concentration. The non-linear ME coefficient was equal to 9.5 V/(cm−Oe2) at Hdc = −1 Oe and 7.5 V/(cm−Oe2) at Hdc = 0 Oe for a structure with 10 cm long Metglas foils.
