Magnetic-fluctuation-driven suppression of spin-orbit hybridization in the surface ferromagnet GdAg/Ag(111)
Ryo Noguchi, Jongkeun Jung, Younsik Kim +2
Magnetic materials hosting topological band structures have attracted intense interest due to the interplay between magnetism and spin-orbit coupling (SOC). Here, using temperature…
Time-, spin-, and angle-resolved photoemission spectroscopy with a 1-MHz 10.7-eV pulse laser
Kaishu Kawaguchi, Kenta Kuroda, Z. Zhao +12
We describe a setup of time-, spin-, and angle-resolved photoemission spectroscopy (tr-SARPES) employing a 10.7-eV (=115.6 nm) pulse laser at 1-MHz repetition rate as a probe ph…
A robust weak topological insulator in a bismuth halide Bi4Br2I2
Ryo Noguchi, Masaru Kobayashi, Kaishu Kawaguchi +11
We apply a topological material design concept for selecting a bulk topology of 3D crystals by different van-der-Waals stacking of 2D topological insulator layers, and find a bismu…
Large anomalous Hall effect induced by weak ferromagnetism in the noncentrosymmetric antiferromagnet
Hiroaki Tanaka, Shota Okazaki, Kenta Kuroda +13
We study the mechanism of the exceptionally large anomalous Hall effect (AHE) in the noncentrosymmetric antiferromagnet by angle-resolved pho…
Selective observation of surface and bulk bands in polar WTe2 by laser-based spin- and angle-resolved photoemission spectroscopy
Yuxuan Wan, Lihai Wang, Kenta Kuroda +12
The electronic state of WTe2, a candidate of type-II Weyl semimetal, is investigated by using laser-based spin- and angle-resolved photoemission spectroscopy (SARPES). We prepare t…
Visualization of optical polarization transfer to photoelectron spin vector emitted from the spin-orbit coupled surface state
Kenta Kuroda, Koichiro Yaji, Ryo Noguchi +4
Similar to light polarization that is selected by a superposition of optical basis, electron spin direction can be controlled through a superposition of spin basis. We investigate…
