Topology is a powerful tool for categorizing magnetization textures by defining a topological index in both two-dimensional (2D) systems, such as thin films or curved surfaces, and in 3D bulk systems. In the emerging field of 3D nanomagnetism, both volume and surface topological numbers must be considered, requiring the identification of a proper global topological […]

The emergence of a large helical orbital texture due to the formation of the surface states at the metallic Co/Al interfaces originating from the orbital Edelstein effect and giving rise to a nonequilibrium orbital accumulation is revealed to produce large current-induced torques, providing an essential theoretical background for the experimental observations. Spin-orbit coupling is found […]

By performing transport simulations on carefully derived Wannier tight-binding models, Janus chromium-based transition-metal dichalcogenide (TMD) monolayers are found to exhibit a spin-orbit torque (SOT) performance comparable to the most efficient two-dimensional materials, while additionally allowing for field-free perpendicular magnetization switching, due to their reduced in-plane symmetry.   The spin–orbit torque (SOT) mechanism represents an innovative […]

We propose the concept of a core-shell composite structure coupled antiparallel via dipolar interaction, as the storage layer in perpendicular-shape-anisotropy magnetic random access memory (PSA MRAM). Benefits compared with a standard PSA MRAM include a reduced write time and the stray field. CoFeB core with a Co shell (height 8 nm; diameters 14 and 20 […]
