Emergence of Giant Magnetic Chirality during Dimensionality Crossover of Magnetic Materials
Dae-Yun Kim, Yun-Seok Nam, Younghak Kim +12
Chirality, an intrinsic preference for a specific handedness, is a fundamental characteristic observed in nature. In magnetism, magnetic chirality arises from the anti-symmetric Dz…
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…
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…
Distinct domain-wall motion between creep and flow regimes near the angular momentum compensation temperature of ferrimagnet
Yuushou Hirata, Duck-Ho Kim, Takaya Okuno +6
We investigate a magnetic domain-wall (DW) motion in two dynamic regimes, creep and flow regimes, near the angular momentum compensation temperature (T_A) of ferrimagnet. In the fl…
