Skyrmion-Skyrmion and Skyrmion-Edge Attractions in Nanostructured Chiral Magnets Authors’ Names:
Magnetic skyrmion, a particle-like topological stable magnetic whirl, hold great promise as an information carrier to build next generation’s high performant memory device in nanostructured chiral magnets. In this scheme, one of the key questions involves the interactions of skyrmion-skyrmion and skyrmion-edge, which governs the ultimate storage density and energy consumption. It has generally ...
متن کاملSkyrmion-like states in two- and three-dimensional dynamical lattices.
We construct, in discrete two-component systems with cubic nonlinearity, stable states emulating Skyrmions of the classical field theory. In the two-dimensional case, an analog of the baby Skyrmion is built on the square lattice as a discrete vortex soliton of a complex field [whose vorticity plays the role of the Skyrmion's winding number (WN)], coupled to a radial "bubble" in a real lattice f...
متن کاملMelting of hexagonal skyrmion states in chiral magnets
Skyrmions are spiral structures observed in thin films of certain magnetic materials (Uchida et al 2006 Science 311 359–61). Of the phases allowed by the crystalline symmetries of these materials (Yi et al 2009 Phys. Rev. B 80 054416), only the hexagonally packed phases (SCh) have been observed. Here the melting of the SCh phase is investigated using Monte Carlo simulations. In addition to the ...
متن کاملExotic skyrmion crystals in chiral magnets with compass anisotropy
The compass-type anisotropy appears naturally in diverse physical contexts with strong spin-orbit coupling (SOC) such as transition metal oxides and cold atomic gases etc, and it has been receiving substantial attention. Motivated by recent studies and particularly recent experimental observations on helimagnet MnGe, we investigate the critical roles of this compass-type anisotropy in modulatin...
متن کاملTwo–Dimensional Magnetic Solitons and Thermodynamics of Quasi–Two–Dimensional Magnets
The article reviews two–dimensional magnetic solitons in a classical weakly– anisotropic Heisenberg magnets. Topological classification, structure, dynamical properties and thermodynamical contribution of 2D solitons to response functions of the magnet are discussed. On the basis of taking in the paper effective equations of motion we calculated the soliton contribution to the dynamical structu...
