Magnetoelectricity in laminate composites of Terfenol-D and 0.52 Pb(Fe1/2Nb1/2)O-3-0.48 PbTiO3 with different orientations

摘要

The effect of the orientation of 0.52 Pb(Fe1/2Nb1/2)O-3-0.48 PbTiO3 single crystal (PFN-PT) on the magnetoelectric (ME) properties in tri-layer laminate composites consisting of TbxDy1-xFe2 alloy and PFN-PT has been studied. The different alpha(E) as a function of applied magnetic field was observed in the laminate composites with different PFN-PT orientations. The origin of alpha(E) dependent on the orientation of PFN-PT is discussed based on an analysis of crystal physics. It was found that the shear strains also play an important role in the ME effect besides the normal strains.
