Description
Summary:The authors have found that the required dc magnetic bias of magnetoelectric (ME) laminates can be significantly altered, by incorporating additional high-permeability μ -metal layers. Investigations have focused on Tb 1 − x Dy x Fe 2 − y ∕ Pb ( Zr 1 − x Ti x ) O 3 ∕ μ -metal laminates. The authors' results show that laminated μ -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.
