Magnetoelectric （ME） composites have recently attracted an ever-increasing interest and provoked a great number of research activities, driven by the potential applications in novel multifunc- tional devices, such as sensors and transducers [1]. Direct ME effect, which describe the appearance of an electric polarization P upon applying a magnetic field H, is usually evaluated by the ME voltage coefficient αME [2]. It is well known that ME effect in com- posites is extrinsic, strongly depending on the intrinsic piezoelec- tric or piezomagnetic properties of constituents,
