Abstract

Since the turn of the millennium, giant magnetoelectric (ME) effects have been found in laminated composites of piezoelectric and magnetostrictive layers. Compared to ME single phase and two phase particulate composites, laminated composites have much higher ME coefficients and are also readily fabricated. Here, we will discuss some of the important advancements that have allowed for dramatic enhancements in the ME voltage and charge coefficients that including: (i) material couples, how the materials properties affect the laminate composites properties. (ii) laminate configurations and operational modes, how the structure enhance the ME effect.
