Magnetic hopfions at room temperature
Kaixin Zhu, Wenli Gao, Zhan Wang +12
The authors demonstrate stable magnetic hopfions at and above room temperature in the chiral magnet Co8Zn8Mn4, created with femtosecond laser pulses and observed using in‑situ TEM,…
Zeta expansion for long-range interactions under periodic boundary conditions with applications to micromagnetics
Andreas A. Buchheit, Jonathan K. Busse, Torsten KeÃler +1
We address the efficient computation of power-law-based interaction potentials of homogeneous -dimensional bodies with an infinite -dimensional array of copies, including the…
Electric-current-assisted nucleation of zero-field hopfion rings
Xiaowen Chen, Dongsheng Song, Filipp N. Rybakov +9
Magnetic hopfions are three-dimensional topological solitons -- knotted, vortex-like spin configurations. In chiral magnets, hopfions can appear as isolated structures or they can…
Linked skyrmions in shifted magnetic bilayer
Sumit Ghosh, Hiroshi Katsumoto, Gustav Bihlmayer +6
Magnetic solitons have recently attracted significant attention due to their intricate physical properties and potential applications in information processing. The majority of the…
Topological invariants of vortices, merons, skyrmions, and their combinations in continuous and discrete systems
Filipp N. Rybakov, Olle Eriksson, Nikolai S. Kiselev
Magnetic vortices and skyrmions are typically characterized by distinct topological invariants. This work presents a unified approach for the topological classification of these te…
