HHG-laser-based time- and angle-resolved photoemission spectroscopy of quantum materials
Takeshi Suzuki, Shik Shin, Kozo Okazaki
Time- and angle-resolved photoemission spectroscopy has played an important role in revealing the non-equilibrium electronic structures of solid-state materials. The implementation…
Photo-excitation band-structure engineering of 2H-NbSe probed by time- and angle-resolved photoemission spectroscopy
Mari Watanabe, Takeshi Suzuki, Takashi Someya +8
We investigated the nonequilibrium electronic structure of 2H-NbSe by time- and angle-resolved photoemission spectroscopy. We find that the band structure is distinctively modu…
Detecting electron-phonon couplings during photo-induced phase transition
Takeshi Suzuki, Yasushi Shinohara, Yangfan Lu +13
Photo-induced phase transitions have been intensively studied owing to the ability to control a material of interest in the ultrafast manner, which can induce exotic phases unable…
Origins of thermal spin depolarization in half-metallic ferromagnet CrO
H. Fujiwara, K. Terashima, M. Sunagawa +15
Using high-resolution spin-resolved photoemission spectroscopy, we observed a thermal spin depolarization to which all spin-polarized electrons contribute. Furthermore we observed…
High temperature antiferromagnetism in Yb based heavy fermion systems proximate to a Kondo insulator
Shintaro Suzuki, Kou Takubo, Kentaro Kuga +9
Given the parallelism between the physical properties of Ce and Yb based magnets and heavy fermions due to the electron-hole symmetry, it has been rather odd that the transition te…
Kondo Resonance in PrTi2Al20: Photoemission spectroscopy and single-impurity Anderson model
M. Matsunami, M. Taguchi, A. Chainani +5
The Kondo resonance at the Fermi level is well-established for the electronic structure of Ce (f1 electron) and Yb (f1 hole) based systems. In this work, we report complementary ex…
Strong valence fluctuation in the quantum critical heavy fermion superconductor beta-YbAlB4: A hard x-ray photoemission study
M. Okawa, M. Matsunami, K. Ishizaka +12
Electronic structures of the quantum critical superconductor beta-YbAlB4 and its polymorph alpha-YbAlB4 are investigated by using bulk-sensitive hard x-ray photoemission spectrosco…
Photoemission evidence for a Mott-Hubbard metal-insulator transition in VO
R. Eguchi, M. Taguchi, M. Matsunami +15
The temperature () dependent metal-insulator transition (MIT) in VO is investigated using bulk sensitive hard x-ray ( 8 keV) valence band, core level, and V 2 re…
Evidence for mass renormalization in LaNiO$"" sub 3_: an in situ soft x-ray photoemission study of epitaxial films
K. Horiba, R. Eguchi, M. Taguchi +5
We investigate the electronic structure of high-quality single-crystal LaNiO (LNO) thin films using in situ photoemission spectroscopy (PES). The in situ high-resolution soft x…
Electronic Structure of Strained Manganite Thin Films with Room Temperature Ferromagnetism Investigated by Hard X-ray Photoemission Spectroscopy
Hidekazu Tanaka, Yasutaka Takata, Koji Horiba +11
We report the bulk sensitive Hard X-ray (hv=5.95keV) core level photoemission spectroscopy to investigate the intrinsic electronic structure of strained (La0.85Ba0.15)MnO3 thin fil…
