Unidirectional gliding of a cycloidal spin structure by an AC magnetic field
Dong Hui Han, Kyoung-Woong Moon, Kab-Jin Kim +1
The dynamics of a cycloidal spin structure driven by an AC magnetic field is theoretically studied in the weak-field limit. A specific model Hamiltonian describing the cycloidal sp…
Identifying intrinsic and extrinsic mechanisms of anisotropic magnetoresistance with terahertz probes
Ji-Ho Park, Hye-Won Ko, Jeong-Mok Kim +7
Identifying the intrinsic and extrinsic origins of magneto-transport in spin-orbit coupled systems has long been a central theme in condensed matter physics. However, it has been e…
Efficient conversion of orbital Hall current to spin current for spin-orbit torque switching
Soogil Lee, Min-Gu Kang, Dongwook Go +9
Spin Hall effect, an electric generation of spin current, allows for efficient control of magnetization. Recent theory revealed that orbital Hall effect creates orbital current, wh…
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…
Perfect optical absorption-enhanced magneto-optic Kerr effect microscopy
Dongha Kim, Young-Wan Oh, Jong-Uk Kim +4
Magnetic and spintronic media have offered fundamental scientific subjects and technological applications. Magneto-optic Kerr effect (MOKE) microscopy provides the most accessible…
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…
