Dzyaloshinskii-Moriya interaction from unquenched orbital angular momentum
Runze Chen, Dongwook Go, Stefan Bluegel +2
Orbitronics is an emerging and fascinating field that explores the utilization of the orbital degree of freedom of electrons for information processing. An increasing number of orb…
Orbital Pumping by Magnetization Dynamics in Ferromagnets
Dongwook Go, Kazuya Ando, Armando Pezo +3
We show that dynamics of the magnetization in ferromagnets can pump the orbital angular momentum, which we denote by orbital pumping. This is the reciprocal phenomenon to the orbit…
First-principles calculation of orbital Hall effect by Wannier interpolation: Role of orbital dependence of the anomalous position
Dongwook Go, Hyun-Woo Lee, Peter M. Oppeneer +2
The position operator in a Bloch representation acquires a gauge correction in the momentum space on top of the canonical position, which is called the anomalous position. We show…
Promoting -based Hall effects by -- hybridization in Gd-based dichalcogenides
Mahmoud Zeer, Dongwook Go, Peter Schmitz +6
We conduct a first-principles study of Hall effects in rare-earth dichalcogenides, focusing on monolayers of the H-phase EuX and GdX, where X = S, Se, and Te. Our predictio…
Oxide layer dependent orbital torque efficiency in ferromagnet/Cu/Oxide heterostructures
Junyeon Kim, Jun Uzuhashi, Masafumi Horio +10
The utilization of orbital transport provides a versatile and efficient spin manipulation mechanism. As interest in orbital-mediated spin manipulation grows, we face a new issue to…
Higher-order Hall response arises from octupole order and scalar spin chirality in a noncollinear antiferromagnet
Adithya Rajan, Tom G. Saunderson, Fabian R. Lux +19
Noncollinear antiferromagnets can generate a transverse electrical response known as the anomalous Hall effect, even though they possess almost no net magnetization. The microscopi…
