研究了0.52 Pb（Fe 1/2Nb 1/2）O3-0.48 PbTiO 3单晶（PFN-PT）取向对TbxDy 1 − xFe 2合金与PFN-PT组成的三层板复合材料磁电性能的影响。不同取向的PFN-PT复合材料的αE随外加磁场的变化规律不同。从晶体物理学的角度分析了αE与PFN-PT取向的关系。结果表明，除了法向应变外，剪切应变对材料的ME效应也起着重要的作用。
The effect of the orientation of 0.52 Pb(Fe1/2Nb1/2)O3–0.48 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 αE as a function of applied magnetic field was observed in the laminate composites with different PFN–PT orientations. The origin of αE 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.
