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…
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,…
Deterministic Néel vector switching of altermagnets via magnetic octupole torque
Seungyun Han, Insu Baek, Kyoung-Whan Kim +2
Altermagnets have recently emerged as promising materials for next-generation spintronic devices. For their device applications, realizing a single-domain configuration is essentia…
Magnetic octupole Hall effect in heavy transition metals
Insu Baek, Seungyun Han, Hyun-Woo Lee
d-wave altermagnets have the magnetic octupole as their primary order parameter. A recent study [Han et al. arXiv 2409.14423 (2024)] demonstrated that magnetic octupole current can…
Harnessing magnetic octupole Hall effect to induce torque in altermagnets
Seungyun Han, Daegeun Jo, Insu Baek +2
d-wave altermagnets have magnetic octupoles as their order parameters [Phys. Rev. X 14, 011019 (2024)]. We theoretically show that magnetic octupoles injected from outside generate…
Nonlinear Orbital and Spin Edelstein Effect in Centrosymmetric Metals
Insu Baek, Seungyun Han, Suik Cheon +1
Nonlinear spintronics combines nonlinear dynamics with spintronics, opening up new possibilities beyond linear responses. A recent theoretical work [Xiao et al., Phys. Rev. Lett. 1…
