Abstract
We consider a multiferroic composite chain consisting of BaTiO3 on the one side and Fe on the other side with a linear magnetoelectric coupling at the interface induced by electrostatic screening. Employing the Landau-Khalatnikov equation for the ferroelectric polarization and the Landau-Lifshitz-Gilbert equation for the magnetization we study theoretically their mutual response to an external time-dependent electric field. We demonstrate for the sixth order ferroelectric potential for BaTiO3 and real parameters for Fe the full magnetization reversal in thin multiferroic chains due to the applied electric field.
