Optical and photoelectrical studies on anisotropic metal-insulator transition of RuAs
Yuki Nakajima, Zenjiro Mita, Hiroshi Watanabe +6
The anisotropic changes in the electronic structure of a metal-to-insulator transition (MIT) material, RuAs, with two-step phase transition are reported by using polarized optical…
Spin-polarized angle-resolved photoelectron spectroscopy of the so-predicted Kondo topological insulator SmB6
Shigemasa Suga, Kazuyuki Sakamoto, Taichi Okuda +13
Undoped and slightly Eu-doped SmB6 show the opening of a gap with decreasing temperature below ~150 K. The spectral shapes near the Fermi level (EF) at 15 K have shown strong incre…
Momentum-Dependent Hybridization Gap and dispersive in-gap state of The Kondo Semiconductor SmB6
Hidetoshi Miyazaki, Tetsuya Hajiri, Takahiro Ito +2
We report the temperature-dependent three-dimensional angle-resolved photoemission spectra of the Kondo semiconductor SmB. We found a difference in the temperature dependence o…
Polaronic behavior of photoelectron spectra of Fe3O4 revealed by both hard X-ray and extremely low energy photons
Masato Kimura, Hidenori Fujiwara, Akira Sekiyama +14
Hard X-ray and extremely low energy bulk-sensitive photoelectron spectroscopy has been performed in the temperature range of 100-330 K for Fe3O4. In the high temperature phase just…
Different Evolution of Intrinsic Gap in Kondo Semiconductors SmB6 and YbB12
J. Yamaguchi, A. Sekiyama, M. Y. Kimura +17
Dependence of the spectral functions on temperature and rare-earth substitution was examined in detail for Kondo semiconductor alloys Sm1-xEuxB6 and Yb1-xLuxB12 by bulk-sensitive p…
Crystalline electric field effects in Ce 3 core-level spectra of heavy-fermion systems: Hard X-ray photoemission spectroscopy on CeNiCoGe
H. J. Im, T. Ito, S. Kimura +3
High-resolution hard X-ray photoemission measurements have been performed to clarify the electronic structure originating from the strong correlation between electrons in bulk Ce 3…
