We have found that laminates of longitudinally magnetized magnetostrictive TERFENOL-D layersand a longitudinally poled piezoelectric Pb(Mg1/3Nb2/3)O-3-PbTiO3 crystal have a giant magnetoelectric voltage coefficient of >430 mV/Oe under a low magnetic bias. Under a resonant drive operation at a frequency of 82.1 kHz, the magnetoelectric coefficient was dramatically increased to similar to18.5 V/Oe. In addition, an ultrahigh magnetic field sensitivity of <10(-11) T has been observed. (C) 2004 American Institute of Physics.
