Competition between uniform ferromagnetism and finite-wave-vector instabilities in square-lattice skyrmion crystals
S. Hayami
We investigate square-lattice skyrmion crystal states in a centrosymmetric spin model with momentum-dependent magnetic interactions, including a uniform ferromagnetic interaction,…
Skyrmion generation via Laguerre-Gaussian beam irradiation in frustrated magnets
Reivienne Jei Laxamana, Satoru Hayami
Since its discovery, the study of magnetic skyrmions has been on the rise. In this paper, we discuss our investigations on the light-induced mechanisms for skyrmion generation in a…
Finite-temperature stability of skyrmion crystals in frustrated magnets: Role of sixfold anisotropy and uniform spin mode in momentum space
Kazuki Okigami, Satoru Hayami
We study the finite-temperature stability of skyrmion crystals in frustrated magnets by analyzing the momentum-space exchange interaction of a classical Heisenberg model on a trian…
Effects of crystal field and momentum-based frustrated exchange interactions on multiorbital square skyrmion lattice
Yan S. Zha, Satoru Hayami
Motivated by recent theoretical predictions of a square-shaped skyrmion lattice (S-SkL) in centrosymmetric tetragonal Ce-based magnets [Yan Zha and Satoru Hayami, Phys. Rev. B 111,…
