Control of the Direction of Magnetization of a Ferromagnetic Layer in Two-Layer Heterostructure Ferromagnet/ferroelectric

We studied two-layer ferromagnet/ferroelectric heterostructures, where iron, cobalt, and nickel were used as ferromagnetic layers, and lithium niobate was used as a ferroelectric substrate. According to our studies, applying an electric field from 10 to 50 V to a ferroelectric lithium niobate substrate is sufficient to register a change in the direction of the magnetization vector of the ferromagnetic layer.
