Aharonov-Casher-induced electric quadrupole of charge-neutral particles
Hojun Lee, Youngjae Jeon, Suik Cheon +1
The paper demonstrates that charge‑neutral particles with magnetic moments acquire an electric quadrupole moment in solids via the Aharonov‑Casher effect, and calculates this effec…
Comparing the orbital angular momentum and magnetic moment of magnons in the Kagome antiferromagnet with negative spin chirality
Youngjae Jeon, Jongjun M. Lee, Suik Cheon +1
The orbital dynamics of magnons have recently drawn interest due to their potential roles in thermal and orbital transport phenomena in magnetic insulators. In this study, we inves…
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…
Enhanced transverse electron transport via disordered composite formation
Sang J. Park, Hojun Lee, Jongjun M. Lee +3
Transverse electron transport in magnetic materials - manifested in effects such as the anomalous Hall and Nernst effects - holds promise for spintronic and thermoelectric applicat…
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…
