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…

Infrared study of valence transition compound YbInCu4 using cleaved surfaces
H. Okamura, T. Michizawa, T. Nanba +1
Optical reflectivity R(w) of YbInCu4 single crystals has been measured across its first-order valence transition at T_v ~ 42 K, using both polished and cleaved surfaces. R(w) measu…

Universal scaling in the dynamical conductivity of heavy fermion Ce and Yb compounds
H. Okamura, T. Watanabe, M. Matsunami +9
Dynamical conductivity spectra s(w) have been measured for a diverse range of heavy-fermion (HF) Ce and Yb compounds. A characteristic excitation peak has been observed in the mid-…
