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…
Collinear ferromagnetism with reduced moment length in kagome magnet Nd3Ru4Al12
Yuki Ishihara, Ryota Nakano, Rinsuke Yamada +14
We determine the magnetic ground state of the kagome lattice magnet Nd3Ru4Al12 by single-crystal neutron diffraction, supported by experiments with polarized neutrons. We identify…
Frustration of harmonic and solitonic helimagnetism on the body-centered tetragonal lattice of GdAlSi
Ryota Nakano, Rinsuke Yamada, Oleg I. Utesov +9
The triangular lattice antiferromagnet (TLAF) with nearest-neighbor exchange interaction is a model platform in the field of frustrated magnetism. Here, anharmonic (`up-up-down') a…
Bond-density-wave orders induced by geometric frustration in the kagome metal CeRu3Si2
Ryo Misawa, Shunsuke Kitou, Rinsuke Yamada +9
Geometric frustration gives rise to vast manifolds of degenerate ground states and competing orders in spin and charge systems. Typically, classical ground states are governed by a…

Weiyi Yun, Ryota Nakano, Ryo Misawa +10
The () family of layered van der Waals (vdW) compounds hosts coexisting magnetic and charge density wave (CDW) orders, yet the interplay bet…
Emergent electric field induced by dissipative sliding dynamics of domain walls in a Weyl magnet
Rinsuke Yamada, Daichi Kurebayashi, Yukako Fujishiro +10
The dynamic motion of topological defects in magnets induces an emergent electric field, as exemplified by the continuous flow of skyrmion vortices. However, the electrodynamics un…
