Epitaxial oxide heterostructures: New design of Energy-Efficient spintronic Devices (NEED)

Vortex structures are common in nature, reaching from swirls in our morning coffee to spiral galaxies in the universe. A polar-vortex and skyrmion are similar to vortexes in liquids but arise in solid materials through ferroelectric moments or magnetic spins, respectively. Once formed, the ensemble can move, deform, and interact with the environment without breaking up ‒ the ideal property for memory and logic devices. In this project the aim is to design a new logic device with robust coupling between magnetism and ferroelectricity. This will be carried out by designing artificial epitaxial heterostructures (i.e. multilayer systems), in which the coupling between ferroelectric and magnetic properties enables the dynamic interaction between these parameters leading to new memory and logic device applications, which will be energy-efficient and robust.
