Commensurability between element symmetry and the number of skyrmions governing skyrmion diffusion in confined geometries
Chengkun Song, Nico Kerber, Jan Rothörl +10
Magnetic skyrmions are topological magnetic structures, which exhibit quasi-particle properties and can show enhanced stability against perturbation from thermal noise. Recently, t…
Interaction between defect and skyrmion in nanodisk
Chengkun Song, Chendong Jin, Haiyan Xia +4
Magnetic skyrmions are topologically protected stable magnetization configurations, which are expected to be a promising candidate as information carrier, while defect is inevitabl…
Dynamics of a magnetic skyrmionium in an anisotropy gradient
Chengkun Song, Chendong Jin, Yunxu Ma +4
Magnetic skyrmionium is a novel magnetization configuration with zero skyrmion number, which is composed by two skyrmions with opposite skyrmion number. Here, we study the dynamics…
Field-tuned spin excitation spectrum of -skyrmion
Chengkun Song, Yunxu Ma, Chendong Jin +4
We study spin-wave excitation modes of skyrmion in a magnetic nanodot under an external magnetic field along -direction using micromagnetic simulations based on Landau-Lifs…
Current-induced motion of twisted skyrmions
Chendong Jin, Chunlei Zhang, Chengkun Song +7
Twisted skyrmions, whose helicity angles are different from that of Bloch skyrmions and Néel skyrmions, have already been demonstrated in experiments recently. In this work, we fir…
Magnetic field direction dependent antiskyrmion motion with microwave electric fields
Chengkun Song, Chendong Jin, Haiyan Xia +4
Magnetic skyrmions are regarded as promising information candidates in future spintronic devices, which have been investigated theoretically and experimentally in isotropic system.…
