The dynamics of a domain wall in ferrimagnets driven by spin-transfer torque
Dong-Hyun Kim, Duck-Ho Kim, Kab-Jin Kim +4
The spin-transfer-torque-driven (STT-driven) dynamics of a domain wall in an easy-axis rare-earth transition-metal ferrimagnet is investigated theoretically and numerically in the…
Magnetic Domain Wall Motion due to AC Bias-Driven Resonances
Duck-Ho Kim, Dong-Hyun Kim, Dae-Yun Kim +4
Most of the existing researches on the dynamics of a domain wall (DW) have focused on the effect of DC biases, where the induced velocity is determined by the bias strength. Here w…
Temperature dependence of magnetic resonance in ferrimagnetic GdFeCo alloys
Takaya Okuno, Se Kwon Kim, Takahiro Moriyama +10
We provide a macroscopic theory and experimental results for magnetic resonances of antiferromagnetically-coupled ferrimagnets. Our theory, which interpolates the dynamics of antif…
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…
Quantitative agreement of Dzyaloshinskii-Moriya interactions for domain-wall motion and spin-wave propagation
Dae-Yun Kim, Nam-Hui Kim, Yong-Keun Park +10
The magnetic exchange interaction is the one of the key factors governing the basic characteristics of magnetic systems. Unlike the symmetric nature of the Heisenberg exchange inte…
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…
