The ME effect in ME composite is generated as a product property of the magnetostrictive effect (magnetic/mechanical effect) in the magnetic phase and the piezoelectric effect (mechanical/electric effect) in the piezoelectric phase. As a result, this two-phase composite material can be represented as (Nan, Bichurin, Dong, Viehland, & Srinivasan, 2008
is the coupling factor (0
1) between the two phases (Nan, 1993
