Project

In silico design of skyrmionics in two-dimensional magnetic materials.

Magnetic skyrmions, the nanoscale topologically swirling spin-textures, hold promise as information carriers for the next generation of low-power spintronic devices. On that path, enhancing their density, stability, and facilitating their creation, manipulation and detection are the key challenges. The recent discovery of intrinsic magnetism in two-dimensional (2D) van der Waals (vdW) materials has radically raised the expectations towards skyrmionic applications. The established ability to broadly tune properties of 2D materials by straining, gating, heterostructuring, makes them an ideal platform for controlling emergent magnetic phases, including skyrmionic ones. The latest experimental observation of ferromagnetic skyrmions in some vdW heterostructures strongly boosted the need for a skyrmionics roadmap in 2D materials that only theoretical simulations can provide, and that is the prime objective of this project. This goal requires developing an advanced multiscale methodology able to account for the manipulations by design in vdW systems, understanding the physics down to the very source of competing magnetic interactions, and detailing the magnetic phase diagrams of 2D materials as a function of mechanical, structural and electronic degrees of freedom, as well as the applied magnetic field and current. Our roadmap will also include the highly sought antiferromagnetic skyrmions, which will definitely promote skyrmionics in 2D materials to the technological paragon level.
