Modeling Multiferroic Materials
Abstract
The study's focus during the last three years was to analytically understand the effects of material properties as well as configurations on the magnetoelectric coupling in monolithic mangetoelectric materials and magnetostrictive/piezoelectric layered composites (denoted as MELC). The models generated during the last three years provide valuable information on understanding the magnetoelectric coupling behavior and hence maximized the magnetoelectric coupling for magnetoelectric system. The first part of the efforts had been devoted to developing continuum level models for both linear and nonlinear single phase magnetoelectric materials, including the solutions to representative problems. For the second effort, we focus on the MELC modeling. A total of six MELC configurations were studied by this model, including three field orientations, longitudinal, transverse, and in-plane, in both 1-D and 2-D plane geometries. By using the modeling analysis, a 3-D design map covering the span of compliance, Poisson's ratio, and piezomagnetic coefficient ratio of the magnetostrictive phases was generated.
