作者已经发现，所需的直流磁偏置的磁电（ME）层压板可以显着改变，通过纳入额外的高磁导率高导磁率层。研究主要集中在Tb_（1-x）Dy_xFe_（2-y）/Pb（Zr_（1-x）Ti_x）O_（3-）/μ金属叠层。作者的研究结果表明，垂直于交流磁场取向的层压高导磁合金层在复合材料中集中磁通，而平行于交流磁场取向的层压高导磁合金层则衰减磁通。这导致（i）所需的直流磁偏置H-dc的显著降低，以及（ii）在低H-dc下ME电压系数的有效增强，高达7.6倍。(c)2006年，美国物理学会。
The authors have found that the required dc magnetic bias of magnetoelectric (ME) laminates can be significantly altered, by incorporating additional high-permeability mu-metal layers. Investigations have focused on Tb1-xDyxFe2-y/Pb(Zr1-xTix)O-3/mu-metal laminates. The authors' results show that laminated mu-metal layers oriented perpendicular to an ac magnetic field concentrate flux in the composite, whereas those parallel to it attenuate flux. This results in (i) a significant decrease in the required dc magnetic bias H-dc, and (ii) an effective enhancement in the ME voltage coefficients at low H-dc, by a factor of up to 7.6.
