Surface-switchable nonreciprocity protected by Fermi arcs in Weyl semimetal TaAs
Dong Li, Yuki M. Itahashi, Ying-Ming Xie +12
Weyl semimetals host topologically protected surface states, known as Fermi arcs, which connect bulk Weyl nodes in momentum space. Both bulk Weyl nodes and Fermi arcs are anticipat…
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…
Polar, checkerboard charge order in bilayer nickelate La3Ni2O7
Ryo Misawa, Shunsuke Kitou, Jian-Ping Sun +6
Competing charge and spin orders are central to uncovering the nature of unconventional superconductivity. Here we utilize synchrotron X-ray diffraction on a high-quality single cr…
Symmetry-Enforced Nodal -Wave Magnets
Moritz M. Hirschmann, Akira Furusaki, Max Hirschberger
Owing to their relevance for spintronics, electronic band splitting and spin-polarization textures in magnets are active areas of research. In non-collinear magnets, alternating sp…
