Pressure-temperature phase diagram of charge ordering in Nd1/2Sr1/2MnO3
P. Maselli, D. Nicoletti, A. Nucara +5
We observe how the charge-ordering (CO) temperature of Nd1/2Sr1/2MnO3 decreases with the external pressure p from 160 K at p = 0 down to 30 K at p ~ 4.5 GPa, by measuring the value…
Combining photoemission and optical spectroscopies for reliable valence determination in YbS and Yb metal
M. Matsunami, A. Chainani, M. Taguchi +13
Hard x-ray photoemission and optical spectroscopies have been performed on YbS and Yb metal to determine the precise -electron occupation. A comparison of the photoemission spec…
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-…
Photogenerated Carriers in SrTiO3 Probed by Mid-Infrared Absorption
H. Okamura, M. Matsubara, K. Tanaka +6
Infrared absorption spectra of SrTiO have been measured under above-band-gap photoexcitations to study the properties of photogenerated carriers, which should play important ro…
Photoinduced spin crossover in Fe-picolylamine complex: A farinfrared study on single crystals
H. Okamura, M. Matsubara, T. Nanba +7
Far-infrared spectroscopy has been performed on [Fe(2-picolylamine)3]Cl2EtOH (Fe-pic) single crystals, to probe changes in the molecular vibrations upon the photoinduced and temper…
