Gate-controlled magnonic-assisted switching of magnetization in ferroelectric/ferromagnetic junctions

摘要

Interfacing a ferromagnet with a polarized ferroelectric gate generates anon-uniform, interfacial spin density coupled to the ferroelectric polarizationallowing so for an electric field control of effective transversal field tomagnetization. Here we study the dynamic magnetization switching behavior ofsuch a multilayer system based on the Landau-Lifshitz-Baryakhtar equation,demonstrating that interfacial magnetoelectric coupling is utilizable as ahighly localized and efficient tool for manipulating magnetism.
