Numerical Computation of Spin-Transfer Torques for Antiferromagnetic Domain walls
Hyeon-Jong Park, Yunboo Jeong, Se-Hyeok Oh +5
We numerically compute current-induced spin-transfer torques for antiferromagnetic domain walls, based on a linear response theory in a tight-binding model. We find that, unlike fo…
Bidirectional spin-wave-driven domain wall motion in antiferromagnetically coupled ferrimagnets
Se-Hyeok Oh, Se Kwon Kim, Jiang Xiao +1
We investigate ferrimagnetic domain wall dynamics induced by circularly polarized spin waves theoretically and numerically. We find that the direction of domain wall motion depends…
Spin-transfer torques for domain walls in antiferromagnetically coupled ferrimagnets
Takaya Okuno, Duck-Ho Kim, Se-Hyeok Oh +13
Antiferromagnetic materials are outstanding candidates for next generation spintronic applications, because their ultrafast spin dynamics makes it possible to realize several order…
Domain wall dynamics in easy-cone magnets
Peong-Hwa Jang, Se-Hyeok Oh, Kyung-Jin Lee
We theoretically and numerically investigate magnetic domain wall dynamics in a nanowire of easy-cone magnet. The easy-cone domain wall exhibits several distinguishing dynamic feat…
Vanishing skyrmion Hall effect at the angular momentum compensation temperature of a ferrimagnet
Yuushou Hirata, Duck-Ho Kim, Se Kwon Kim +14
Charged particles exhibit the Hall effect in the presence of magnetic fields. Analogously, ferromagnetic skyrmions with non-zero topological charges and finite fictitious magnetic…
Low magnetic damping of ferrimagnetic GdFeCo alloys
Duck-Ho Kim, Takaya Okuno, Se Kwon Kim +12
We investigate the Gilbert damping parameter for rare earth (RE)-transition metal (TM) ferrimagnets over a wide temperature range. Extracted from the field-driven magnetic domain-w…
Spin-wave propagation in cubic anisotropic materials
Koji Sekiguchi, Seo-Won Lee, Hiroaki Sukegawa +4
The information carrier of modern technologies is the electron charge whose transport inevitably generates Joule heating. Spin-waves, the collective precessional motion of electron…
Coherent Terahertz Spin-Wave Emission Associated with Ferrimagnetic Domain Wall Dynamics
Se-Hyeok Oh, Se Kwon Kim, Dong-Kyu Lee +5
We theoretically study the dynamics of ferrimagnetic domain walls in the presence of Dzyaloshinskii-Moriya interaction. We find that an application of a DC magnetic field can induc…
Fast domain wall motion induced by antiferromagnetic spin dynamics at the angular momentum compensation temperature of ferrimagnets
Kab-Jin Kim, Se Kwon Kim, Takayuki Tono +11
Antiferromagnetic spintronics is an emerging research field which aims to utilize antiferromagnets as core elements in spintronic devices. A central motivation toward this directio…
Antiferromagnetic domain wall motion driven by spin-orbit torques
Takayuki Shiino, Se-Hyeok Oh, Paul M. Haney +4
We theoretically investigate dynamics of antiferromagnetic domain walls driven by spin-orbit torques in antiferromagnet/heavy metal bilayers. We show that spin-orbit torques drive…
