Enhancement in the response of Pb(Zr,Ti)O3/Terfenol-D/Metglas magnetoelectric laminate composites

The magnetic field response results on a five-layer structure given as Metglas /Terfenol-D/Pb(Zr,Ti)O3/Terfenol-D/Metglas were reported. Due to its high permeability, Metglas can be incorporated as the third phase into conventional Pb(Zr,Ti)O3/Terfenol-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 μm 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.
