Robust topological surface states in skyrmion-host magnets Eu(Ga,Al)4: evidence for dual topology
Yuki Arai, Kosuke Nakayama, Takemi Kato +10
The interplay between real-space topology such as magnetic skyrmions and momentum-space topology characterized by topological surface states (TSSs) is predicted to realize novel ph…

Origin of multiple skyrmion phases in EuAl4
Y. Arai, K. Nakayama, A. Honma +6
The Dzyaloshinskii-Moriya (DM) interaction has been considered essential for skyrmion formation, however, the discovery of skyrmion lattices (SkLs) in nominally centrosymmetric mat…

Spontaneous Anomalous Hall Effect at Room Temperature in Antiferromagnetic Material NbMnAs
Yuki Arai, Junichi Hayashi, Keiki Takeda +4
Recent studies have shown that certain antiferromagnetic (AFM) materials with the same symmetry breaking as ferromagnets can generate sufficiently large ferromagnetic (FM) response…
