Multiple- spin textures induced by spiral--staggered interference in one-dimensional itinerant magnets
Satoru Hayami, Kazuki Okigami
We theoretically investigate multiple- magnetic states emerging from the interference between finite- spiral and staggered spin modulations in a one-dimensional itinerant ele…
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…
Incommensurate broken helix induced by nonstoichiometry in the axion insulator candidate EuInAs
Masaki Gen, Yukako Fujishiro, Kazuki Okigami +9
Zintl phase EuInAs has garnered growing attention as an axion insulator candidate, triggered by the identification of a commensurate double- broken-helix s…
