Due to its high permeability, Metglas can be incorporated as the third phase into conventional Pb（Zr, Ti）OJTerfenol-D laminates, which results in a stronger magnetoelectric（ME） response. The increase in Metglas thickness significantly influences the ME response as well. The ME voltage coefficient for a structure with a 150 grn thick Metglas layer on both sides of Terfenol-D/Pb（Zr, Ti）O3 laminates at 1 kHz was found to be 1.2 V/cmOe at dc magnetic bias field of 590 Oe under an ac magnetic drive of 1 Oe, which was notably higher in comparison to similar structures with other different Metglas thickness.

文摘The magnetic field response results on a five-layer structure given as Metglas/Terfenol-D/ Pb（Zr,Ti）O3frerfenol-D/Metglas were reported.
