Abstract

A theoretical model is developed for the magnetoelectric (M-E) voltage coefficient α for a magnetostrictive-piezoelectric layered composite (MPLC). Three field orientations; including longitudinal, transverse, and in-plane, with two in plane geometries, 2D and 1D, are presented and studied with respect to the volume fraction of piezoelectric phase and the material properties of magnetostrictive phase. Results show that the phase volume fraction to achieve maximum M-E coupling effect is determined by the compliance of magnetostrictive phase. Higher compliance values shift α' peaks to lower piezoelectric volume fraction and weaken α' values. This study also investigates the influence of the piezomagnetic coefficient q₃₃ and the ratio q₃₃/q₃₁. For constant ratio of q₃₃/q₃₁, larger q₃₃ values increase the M-E coupling effect. On the contrary, changing the ratio of q₃₃/q₃₁ changes the relative α' values for each of the six cases. This demonstrates that the ratio q₃₃/q₃₁ strongly influences the selection of MPLC configurations to produce the largest α'.
