Intra-atomic magnetic octupoles and their coupling to cluster magnetic octupoles in Chiral antiferromagnets MnSn
Dohoon Park, Seungyun Han, Hyun-Woo Lee
We demonstrate that MnSn hosts finite intra-atomic magnetic octupoles (AMOs) in addition to the well-established cluster magnetic octupole (CMO) . In c…
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…
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…
Gigantic current control of coercive field and magnetic memory based on nm-thin ferromagnetic van der Waals Fe3GeTe2
Kaixuan Zhang, Seungyun Han, Youjin Lee +11
Controlling magnetic states by a small current is essential for the next-generation of energy-efficient spintronic devices. However, it invariably requires considerable energy to c…
