Tunable competing optical excitation pathways in the topological surface states of BiTe
Shin Yokoyama, Takahito Takeda, Nagi Suzuki +9
Understanding coherent optical responses of topological surface states (TSSs) requires disentangling excitation pathways from the electronic band structure. Here, using angle-resol…
Termination-Dependent Surface States and Magnetic Fingerprints of Chiral Helimagnet Cr1/3TaS2
Bo Liang, Xue Li, Congcong Le +36
Chiral helimagnets based on intercalated transition-metal dichalcogenides, characterized by nano-scale spin ordering, provide a powerful route to engineer chiral spin textures (e.g…
Strongly Anisotropic Spin and Orbital Rashba Effect at a Tellurium - Noble Metal Interface
B. Geldiyev, M. Ünzelmann, P. Eck +19
We study the interplay of lattice, spin and orbital degrees of freedom in a two-dimensional model system: a flat square lattice of Te atoms on a Au(100) surface. The atomic structu…
Laser-based angle-resolved photoemission spectroscopy with micrometer spatial resolution and detection of three-dimensional spin vector
Takuma Iwata, T. Kousa, Y. Nishioka +11
We have developed a state-of-the-art apparatus for laser-based spin- and angle-resolved photoemission spectroscopy with micrometer spatial resolution (micro-SARPES). This equipment…
Observation of spin-momentum-layer locking in centrosymmetric BiOI
Ke Zhang, Shixuan Zhao, Zhanyang Hao +16
Spin polarization effects in nonmagnetic materials are generally believed as an outcome of spin-orbit coupling provided that the global inversion symmetry is lacking, also known as…
Spin-polarized Weyl cones and gigantic anomalous Nernst effect in ferromagnetic Heusler films
Kazuki Sumida, Yuya Sakuraba, Keisuke Masuda +8
Weyl semimetals are characterized by the presence of massless band dispersion in momentum space. When a Weyl semimetal meets magnetism, large anomalous transport properties emerge…
