Magnetoelectric coupling in multiferroic laminated plates with giant magnetostrictive material layers

摘要

We present an analytical model to predict the magnetoelectric (ME) effect in multiferroic laminated plates consisting of piezoelectric material and giant magnetostrictive material (GMM). The nonlinear behavior of GMM is taken into account by employing a simple quadratic constitutive relation. Both static and dynamic cases are considered. It is found that: (1) the dependence of ME effect on the applied magnetic field is quite different from that reported in the previous analysis; and (2) one part of the induced electric field has a frequency that is double the driving frequency of the applied magnetic field. The results indicate that multiferroic laminated plates with GMM layers have potential applications in multipliers and energy harvesters.
