Paper Abstract

The converse magnetoelectric effect of an asymmetric Piezo-fiber/Metglas bilayer laminate composite subjected to mechanical prestress is presented. The mechanical prestress is applied by either dc electric voltage bias or direct mechanical load bias. It is found that a mechanical prestress strongly influences the converse magnetoelectric coupling response. The optimum dc magnetic field bias shifts with different prestress and compressive stress requires higher dc magnetic field bias. Additionally, an optimum prestress exists to maximize the converse magnetoelectric response under certain dc magnetic field bias ranges. Therefore, in order to integrate magnetoelectric composite into actual structures, a proper prestress needs to be employed to maximize the CME coefficient.
