Ferrochiral, antiferrochiral, and ferrichiral skyrmion crystals in an itinerant honeycomb magnet
Ryota Yambe, Satoru Hayami
Topological spin textures, such as a skyrmion crystal, are a source of unusual physical phenomena owing to the interplay between magnetism and topology. Since physical phenomena de…
Engineering a skyrmion crystal in ferromagnetic/antiferromagnetic bilayers free from the DM interaction
Kazuki Okigami, Ryota Yambe, Satoru Hayami
We theoretically propose a new stabilization mechanism of a skyrmion crystal (SkX) in a bilayer triangular lattice system consisting of the ferromagnetic and the antiferromagnetic…
Skyrmion crystal under point group: Role of out-of-plane Dzyaloshinskii-Moriya interaction
Satoru Hayami, Ryota Yambe
The Dzyaloshinkii-Moriya (DM) interaction that originates from relativistic spin-orbit coupling in noncentrosymmetric magnets is a source of topological spin textures. We theoretic…
Helicity locking of square skyrmion crystal in a centrosymmetric lattice system without vertical mirror symmetry
Satoru Hayami, Ryota Yambe
We theoretically investigate the stability of a square skyrmion crystal (SkX) in a centrosymmetric tetragonal lattice structure with the emphasis on the role of the magnetic anisot…
Effective spin model in momentum space: Toward a systematic understanding of multiple- instability by momentum-resolved anisotropic exchange interactions
Ryota Yambe, Satoru Hayami
Multiple- magnetic states, such as a skyrmion crystal, become a source of unusual transport phenomena and dynamics. Recent theoretical and experimental studies clarify that such…
