2D magnetic memories: scalable growth and hybrid electrical operation – MNEMOSYN

MNEMOSYN will develop and optimize techniques to grow large-scale two-dimensional (2D) magnetic materials, co-integrated with strong spin-orbit coupling materials, graphene and 2D ferroelectrics in high-quality multilayer van der Waals heterostructures. The main objective is to demonstrate a large power reduction for magnetization actuation by spin-orbit-torques (SOT) and by multiferroic proximity effects. The consortium will benefit from state-of-the-art molecular beam epitaxy equipment provided by three different partners to accelerate the study of various selected materials combinations in a concerted fashion. Experimental developments will be supported and guided by simulations combining first-principles calculations with large-scale simulations of SOT figures of merit on properly designed Hamiltonians. The outcomes of the project will consist in establishing the best growth and integration conditions, the corresponding upper limit of SOTs efficiency, and the demonstration of 2D multiferroicity, targeting room-temperature operation and scalable fabrication of memory building blocks. The feasibility of further fab developments will be also ascertained to achieve higher technology readiness levels (TRL).
