Observation of g-wave altermagnetic multipole
Ryo Misawa, Rikuto Oiwa, Shunsuke Kitou +16
Over the past few years, altermagnets have emerged as a new class of collinear magnets with broken time-reversal symmetry, offering novel opportunities for spintronics beyond conve…
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…
Spinless electric toroidal multipoles in ferroaxial revealed by symmetry-adapted closest Wannier analysis
Yu Xie, Rikuto Oiwa, Satoru Hayami
From a symmetry perspective, ferroaxial order belongs to the same symmetry as time-reversal-even pseudovectors. Experimentally, is known to undergo a displaci…
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…
Light-induced nonlinear Edelstein effect under ferroaxial ordering
Akimitsu Kirikoshi, Satoru Hayami
Ferroaxial ordering, a spontaneous rotational distortion of the atomic arrangement, brings about a cross-product-type spin-orbit coupling (SOC) manifested as an electric toroidal d…
Finite- antiferrotoroidal and ferritoroidal order in a distorted kagome structure
Akimitsu Kirikoshi, Satoru Hayami
A highly geometrically frustrated lattice structure such as a distorted kagome (or quasikagome) structure enriches physical phenomena through coupling with the electronic structure…
Perfectly harmonic spin cycloid and multi- textures in the Weyl semimetal GdAlSi
Ryota Nakano, Rinsuke Yamada, Juba Bouaziz +18
A fundamental question concerns how topological electronic states are influenced by many-body correlations, and magnetic Weyl semimetals represent an important material platform to…
Exploring topological spin order by inverse Hamiltonian design: A new stabilization mechanism for square skyrmion crystals
Kazuki Okigami, Satoru Hayami
We propose a framework to construct a real-space spin model based on the inverse Hamiltonian design. The method provides an efficient way of realizing unconventional topological sp…
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…
