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…

Four-Spin Interactions as a Route to Multiple-Q Topological Magnetic Order
Kazuki Okigami, Satoru Hayami
We investigate the role of four-spin interactions in stabilizing exotic multiple- topological spin textures and demonstrate their ability to realize a skyrmion crystal. While su…
