Differently from magnetoelectric (ME) crystal families (e.g., Cr 2 O 3 and phosphates) to which the ME effect is intrinsic, multiferroic composites such as ferrite/piezoelectric ceramic composites exhibit extrinsic ME effect which is known as a "product property" resulted from the interaction between the ferrite and piezoelectric ceramic phases, and the extrinsic ME effect is a "0 + 0 > 0 composite effect", since neither phase is magnetoelectric. In this article, based on the expressions derived by using a physics-based Green's function technique, we discuss the extrinsic ME effect in a few piezoelectric/magnetostrictive composites including ceramic-matrix and polymer-matrix composites.
