We have found that laminates of longitudinally magnetized magnetostrictive TERFENOL-D layersand a longitudinally poled piezoelectric Pb(Mg1∕3Nb2∕3)O3-PbTiO3 crystal have a giant magnetoelectric voltage coefficient of >430mV∕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 ∼18.5V∕Oe. In addition, an ultrahigh magnetic field sensitivity of <10−11T has been observed.
