Catalog of Altermagnetism in Magnetic Wallpaper/Space Groups and Nonsymmorphic Altermagnets
Congcong Le, Fan Cui, Iao-Fai Io +3
Conventional altermagnetism, characterized by compensated collinear spin alignment and spin splitting, exhibits identical spin states at opposite momenta. In this work, we employ a…
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…
Observation and Control of Moiré-Tailored Topological Dirac States
R. Ganser, M. P. T. Masilamani, B. Geldiyev +6
Moiré heterostructures provide a powerful framework for tailoring electronic band structures via controlled long-range periodic superlattice potentials. Beyond widely studied moir…
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…
Spiral-induced Anomalous Hall Effect from Odd-parity Spin-nodal Lines
Shun Okumura, Moritz M. Hirschmann, Yukitoshi Motome
Spin spirals represent a fundamental class of noncollinear yet coplanar magnetic structures that give rise to diverse emergent phenomena reflecting spin chirality. We investigate m…
Topological Metal-Insulator Transition within the Ferromagnetic state
Ola Kenji Forslund, Chin Shen Ong, Moritz M. Hirschmann +20
A major challenge in condensed matter physics is integrating topological phenomena with correlated electron physics to leverage both types of states for next-generation quantum dev…
