Spin-orbit torque switching of perpendicular magnetization in ferromagnetic trilayers
Dong-Kyu Lee, Kyung-Jin Lee
In ferromagnetic trilayers, a spin-orbit-induced spin current can have a spin polarization of which direction is deviated from that for the spin Hall effect. Recently, magnetizatio…
Effect of inhomogeneous Dzyaloshinskii-Moriya interaction on antiferromagnetic spin-wave propagation
Seung-Jae Lee, Dong-Kyu Lee, Kyung-Jin Lee
We investigate the effect of inhomogeneous Dzyaloshinskii-Moriya interaction (DMI) on antiferromagnetic spin-wave propagation theoretically and numerically. We find that antiferrom…
Long spin coherence length and bulk-like spin-orbit torque in ferrimagnetic multilayers
Jiawei Yu, Do Bang, Rahul Mishra +14
Ferromagnetic spintronics has been a main focus as it offers non-volatile memory and logic applications through current-induced spin-transfer torques. Enabling wider applications o…
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…
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…
