Converse Magnetoelectric Coefficient of Terfenol-D/PZT/Terfenol-D Laminated Magnetoelectric Composite

Article Preview

Abstract:

The converse magnetoelectric coefficient (CME coefficient) of LT（The magnetization direction of Terfenol-D is vertical with the polarization direction of PZT) Terfenol-D/PZT/ Terfenol-D magnetoelectric composite is calculated by means of equivalent circuit method. The CME coefficient equation shows that ME coefficient is decided by performance parameters and the volume ratio of Terfenol-D and PZT. The calculation results predict that when the PZT thickness ratio n is 0.44, the maximum CME coefficient is 0.047G/V. And the equation is applied to the CME coefficient calculation of the same specifications and different structure of LT laminate magnetoelectric composites.
