Description
Orbitronics has recently emerged as a valid alternative to the field of spintronics, with the orbital degree of freedom serving as the main variable for transportation and magnetization manipulation. Currently, the majority of envisioned applications in orbitronics are associated with the generation and utilization of the orbital currents hosted by non-magnetic bulk materials. On the other hand, magnetic two-dimensional (2D) materials are steadily moving to the center of materials research owing to their outstanding properties and prospects in novel magnetic applications. In my talk, I will discuss the interplay of topological features in the electronic structure of 2D magnets with ground-state and current-induced orbital magnetism and orbital currents. Taking as an example selected families of magnetic dichalcogenides, I will demonstrate how the electronic structure engineering of p-d-f hybridization in two dimensions can give rise to prominent topological orbital response, manifesting in the phenomena of current-induced orbital torques on the magnetization and pumping of orbital currents by magnetization dynamics.
