Computational characterization of magneto‐electric composites: the role of ferroelectric pre‐polarization. Issue 1 (21st October 2015) - Labusch, Matthias
Abstract The interaction between electric and magnetic fields enables smart devices which can find applications in sensor technology and data storage. Materials showing magneto‐electric (ME) coupling combine different ferroic characteristics. In the present contribution we focus on composites, which combine ferroelectric and ferromagnetic phases due to strain couplings, such that they generate a strain‐induced ME coupling. We derive a two‐scale homogenization approach for the determination of effective properties in consideration of microscopic morphologies. Furthermore, we demonstrate the strong influence of ferroelectric polarization states on the ME‐coefficient by modeling the switching of remanent polarizations on the microscale.
