Symmetry-Tunable Skyrmions and Merons in Magnetic Nanodisks via Spatially Engineered Anisotropy
X. D. Wang, J. F. Oliveira da Silva, Z. H. Tao +3
We demonstrate that spatially engineered magnetic anisotropy can stabilize skyrmion and meron spin textures in magnetic nanodisks even in the absence of Dzyaloshinskii-Moriya inter…
Reversible and irreversible dynamical topological transitions of magnetic Hopfions
S. Y. Lu, H. M. Dong, D. X. Yu +1
Magnetic Hopfions are three-dimensional (3D) topological solitons characterized by a nonzero Hopf invariant and offer a promising platform for 3D spintronics. While their static st…
Ultrafast manipulation of magnetic skyrmions by microwave fields
Xingdi Wang, Haiming Dong, Kai Chang
We theoretically investigate the inertial dynamics of magnetic skyrmions driven by circularly polarized microwave-induced inverse Faraday effect (MIFE). By incorporating an inertia…
Tilted chiral spin textures in confined nanostructures with in-plane magnetic anisotropy
Wenlei Fu, Haiming Dong, Kai Chang
We demonstrate that nanoconfinement effects and in-plane magnetic anisotropy (IMA) can lead to tilted chiral spin textures in magnetic nanostructures, based on the analysis and sim…
