Pressure-tuning of the c-f hybridization in Yb metal detected by infrared spectroscopy up to 18 GPa
H. Okamura, K. Senoo, M. Matsunami +1
It has been known that the elemental Yb, a divalent metal at mbient pressure, becomes a mixed-valent metal under external pressure, with its valence reaching ~2.6 at 30 GPa. In thi…
Photoemission study of (VM)O (M=Cr, Ti)
S. -K. Mo, H. -D. Kim, J. D. Denlinger +8
We present high-resolution bulk-sensitive photoemission spectra of (VM)O (M=Cr, Ti). The measurements were made for the paramagnetic metal (PM), paramagnetic in…
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…
Evolution of the electronic structure across the filling-control and bandwidth-control metal-insulator transitions in pyrochlore-type Ru oxides
J. Okamoto, S. -I. Fujimori, T. Okane +4
We have performed photoemission and soft x-ray absorption studies of pyrochlore-type Ru oxides, namely, the filling-control system SmCaRuO and the bandwidth-con…
High-order Dy multipole motifs observed in DyB2C2 with resonant soft x-ray Bragg diffraction
A. M. Mulders, U. Staub, V. Scagnoli +6
Resonant soft x-ray Bragg diffraction at the Dy M4,5 edges has been exploited to study Dy multipole motifs in DyB2C2. Our results are explained introducing the intra-atomic quadrup…
