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.
