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…
Meron-antimeron crystals in noncentrosymmetric itinerant magnets on a triangular lattice
Satoru Hayami, Ryota Yambe
Multiple- magnetic states often induce nontrivial topological spin textures, such as a skyrmion and a hedgehog. We theoretically investigate yet another multiple- state with…
Field-Direction Sensitive Skyrmion Crystals in Cubic Chiral Systems: Implication to -Electron Compound EuPtSi
Satoru Hayami, Ryota Yambe
We theoretically study the stability of magnetic skyrmion crystals (SkXs) in chiral cubic antiferromagnets with the EuPtSi hosting unconventional nanometric SkXs in mind. By perfor…
Degeneracy Lifting of Néel, Bloch, and Anti-Skyrmion Crystals in Centrosymmetric Tetragonal Systems
Satoru Hayami, Ryota Yambe
A skyrmion crystal has internal degrees of freedom in terms of vorticity and helicity, which gives rise to fascinating types of skyrmion phases (Néel, Bloch, and anti-skyrmion). We…
Double- Chiral Stripe in the - Model with Strong Spin-Charge Coupling
Ryota Yambe, Satoru Hayami
We investigate the stability of multiple- spiral states in - electron systems with the strong spin-charge coupling. By using variational calculations on a square lattice,…
