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…
Large Seebeck coefficient driven by "pudding mold" flat band in hole-doped CuRhO
Amitayush Jha Thakur, Maximilian Thees, Franck Fortuna +7
We report the measurement, using angle-resolved photoemission spectroscopy, of the metallic electronic structure of the hole-doped thermoelectric oxide CuRhMgO.…
Electronic phase diagram of Cr-doped VO2 epitaxial films studied by in situ photoemission spectroscopy
D. Shiga, X. Cheng, T. T. Kim +5
Through in situ photoemission spectroscopy (PES), we investigated the changes in the electronic structure of Cr-doped VO2 films coherently grown on TiO2 (001) substrates. The elect…
Electronic band structure of Ti2O3 thin films studied by angle-resolved photoemission spectroscopy
Naoto Hasegawa, Kohei Yoshimatsu, Daisuke Shiga +5
Ti2O3 exhibits a unique metal-insulator transition (MIT) at approximately 450 K over a wide temperature range of ~ 150 K. This broad MIT accompanied by lattice deformation differs…
Electronic structure of SrTiVO films studied by photoemission spectroscopy: Screening for a transparent electrode material
Tatsuhiko Kanda, Daisuke Shiga, Ryu Yukawa +8
This study investigated the electronic structure of SrTiVO (STVO) thin films, which are solid solutions of strongly correlated transparent conductive oxide (TCO) Sr…
Molecular beam epitaxy growth of the highly conductive oxide SrMoO
Hiroshi Takatsu, Naoya Yamashina, Daisuke Shiga +5
SrMoO is a promising material for its excellent electrical conductivity, but growing high-quality thin films remains a challenge. Here we synthesized epitaxial films of SrMoO$_…
Electronic structure of a 3x3-ordered silicon layer on Al(111)
Y. Sato, Y. Fukaya, M. Cameau +11
Electronic structure of the 3x3 ordered-phase of a silicon (Si) layer on Al(111) has been studied by angle resolved photoemission spectroscopy (ARPES) technique using synchrotron r…
Thickness dependence of electronic and crystal structures in VO ultrathin films: suppression of the collaborative Mott-Peierls transition
D. Shiga, B. E. Yang, N. Hasegawa +7
Through photoemission spectroscopy, we investigated the change in the electronic and crystal structures of dimensionality-controlled VO films coherently grown on Ti…
Relationship between charge redistribution and ferromagnetism at the heterointerface between perovskite oxides LaNiO and LaMnO
Miho Kitamura, Masaki Kobayashi, Enju Sakai +10
To investigate the relationship between the charge redistribution and ferromagnetism at the heterointerface between perovskite transition-metal oxides LaNiO (LNO) and LaMnO…
Emergence of metallic monoclinic states of VO films induced by K deposition
Daisuke Shiga, Makoto Minohara, Miho Kitamura +3
In order to study the origin of metallization of VO induced by electron injection, we deposit K atoms onto the surface of VO films grown on TiO (001) substrates, and we…
