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).

MNEMOSYN将开发和优化技术，以生长大规模的二维（2D）磁性材料，与强自旋轨道耦合材料，石墨烯和2D铁电体共同集成在高质量的多层货车德瓦尔斯异质结构中。主要目的是证明一个大的功率减少磁化驱动的自旋轨道转矩（SOT）和多铁性邻近效应。该联合体将受益于三个不同合作伙伴提供的最先进的分子束外延设备，以协调一致的方式加速对各种选定材料组合的研究。实验的发展将支持和指导相结合的第一性原理计算与大规模的模拟SOT的优点数字正确设计的哈密顿量的模拟。该项目的成果将包括建立最佳的生长和集成条件，SOT效率的相应上限，以及2D多铁性的演示，目标是室温操作和存储器构建块的可扩展制造。进一步晶圆厂发展的可行性也将得到确认，以达到更高的技术准备水平（TRL）。
