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…
Alternative understanding of the skyrmion Hall effect based on one-dimensional domain wall motion
Kyoung-Woong Moon, Jungbum Yoon, Changsoo Kim +4
A moving magnetic skyrmion exhibits transverse deflection. This so-called skyrmion Hall effect has been explained by the Thiele equation. Here, we provide an alternative interpreta…
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…
Double bit in-plane magnetic skyrmions on a track
Kyoung-Woong Moon, Jungbum Yoon, Changsoo Kim +1
A magnetic skyrmion isusually refers to a twisted spin texture surrounded by uniformly aligned out-of-plane spinsin the background of a uniformly magnetized state. The invariance o…
Asymmetric skyrmion Hall effect in systems with a hybrid Dzyaloshinskii-Moriya interaction
Kyoung-Whan Kim, Kyoung-Woong Moon, Nico Kerber +2
We examine the current-induced dynamics of a skyrmion that is subject to both structural and bulk inversion asymmetry. There arises a hybrid type of Dzyaloshinskii-Moriya interacti…
