Anatomy of the modern theory of orbital magnetism from first-principles: term-by-term analysis in the gauge-covariant formalism
Hojun Lee, Insu Baek, Mirco Sastges +3
We present an in-depth analysis of the orbital magnetism by means of the so-called modern theory based on the Berry phase across distinct classes of materials-d transition metals,…
Modern Approach to Orbital Hall Effect Based on Wannier Picture of Solids
Mirco Sastges, Insu Baek, Hojun Lee +3
The orbital Hall effect (OHE) and its key figure of merit, the orbital Hall conductivity (OHC), are central to the emerging field of orbitronics. The OHC is conventionally computed…
Itinerant Orbital Hall Effect Mechanism Leading to Large Negative Orbital Torques from Light Metal Vanadium
Nikhil Vijayan, Durgesh Kumar, Ao Du +13
The orbital Hall effect (OHE) has attracted significant attention for developing energy-efficient electronic devices. However, utilizing it in fast, low-power devices requires an e…
Giant orbital Zeeman effects in a magnetic topological van der Waals interphase
Tobias Wichmann, Mirco Sastges, Keda Jin +10
Van der Waals (vdW) heterostructures allow the engineering of electronic and magnetic properties by the stacking different two-dimensional vdW materials. For example, orbital hybri…
