Using the finite element method for the investigation of the magnetoelectric effect in 2-2 laminar composites

In this article, the Finite Element Method was applied to investigate the magnetic and electrical responses of laminar composites based on Tb x Dy 1− x Fe 2 (TERFENOL-D) and PbZr x Ti 1− x O 3 (PZT). The simulations show that the laminar composites at the so-called 2-2 connectivity provide a substan...

Summary:In this article, the Finite Element Method was applied to investigate the magnetic and electrical responses of laminar composites based on Tb x Dy 1− x Fe 2 (TERFENOL-D) and PbZr x Ti 1− x O 3 (PZT). The simulations show that the laminar composites at the so-called 2-2 connectivity provide a substantial magnetoelectric response when excited by superimposed DC and AC magnetic fields. It is found that the output signal is optimized for AC magnetic fields whose frequencies match with some of that vibration (harmonics) modes of the piezoelectric layer.
