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…
Directional Spin-wave Propagation in the Skyrmion Chain
Chunlei Zhang, Chendong Jin, Jinshuai Wang +4
The Dzyaloshinskii-Moriya interaction (DMI), favoring a chiral spin structure like the skyrmion, gives rise to the nonreciprocal propagation of spin waves. We investigate the propa…
Metastable magnetic bubble in [Co/Pd]4/Py multilayers
Yurui Wei, Chengkun Song, Yunxu Ma +9
Magnetic bubbles are topologically spin textures that offering the interesting physics and great promise for next-generation information storage technologies. The main obstacles so…
