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…
Microwave excitations and hysteretic magnetization dynamics of stripe domain films
Meihong Liu, Qiuyue Li, Chengkun Song +11
FeNi films with the stripe domain (SD) pattern are prepared by electrodeposition and sputtering methods. The magnetic domain, static magnetic parameters, and quality factor, as wel…
