Abstract

The influence of magnetic fields on the mechanical loss (Q^-1) of Terfenol-D/PbZr_0.52Ti_0.48O₃/Terfenol-D three-layer laminated composites is investigated systemically using the technique for measuring the resonance magnetoelectric (ME) effect. The results indicate that Q^-1 varies non-monotonically with dc magnetic fields and shows a maximum near 500 Oe for all the samples with different layer thickness ratios (n) of Terfenol-D (Tb_0.3Dy_0.7Fe _1.92). Considering various kinds of mechanical energy dissipation, it is found that Q^-1 is mainly dominated by the mechanical damping due to the domain wall motion in Terfenol-D under the actions of dc and ac magnetic fields as well as the stress at the interface. In addition, the effect of eddy current losses on the energy dissipation of the system is also discussed.
