Multilayer composites of a piezoelectric material and a piezomagnetic material can be designed to exhibit magnetoelectric (ME) effect. Such a composite is electrically polarized when it is placed in a magnetic field or is magnetized when an electric field is applied to it. Since the phases have anisotropic properties, the resulting ME coefficient depends on the boundary conditions of the composite. We have modelled four simple cases of two-layer structures of these composites and derived the theoretical expression for the ME coefficient for each arrangement.
