Intrinsic Correlated Electronic Structure of CrO2 Revealed by Hard X-ray Photoemission Spectroscopy

M. Sperlich, C. König, G. Güntherodt +14

Bulk-sensitive hard x-ray photoemission spectroscopy (HAXPES) reveals for as-grown epitaxial films of half-metallic ferromagnetic CrO2(100) a pronounced screening feature in the Cr…

Phonon Softening and Dispersion in EuTiO3

David S. Ellis, Hiroshi Uchiyama, Satoshi Tsutsui +4

We measured phonon dispersion in single crystal EuTiO using inelastic x-ray scattering. A structural transition to an antiferrodistortive phase was found at a critical temperat…

Pressure suppression of unconventional charge-density-wave state in PrRu4P12 studied by optical conductivity

H. Okamura, N. Ohta, A. Takigawa +12

Optical conductivity s(w) of PrRu4P12 has been studied under high pressure to 14 GPa, at low temperatures to 8 K, and at photon energies 12 meV-1.1 eV. The energy gap in s(w) at am…

Soft and Isotropic Phonons in PrFeAsO_{1-y}

T. Fukuda, A. Q. R. Baron, H. Nakamura +9

Phonons in single crystals of PrFeAsO_{1-y} are investigated using high-resolution inelastic x-ray scattering and ab initio pseudopotential calculations. Extensive measurements of…

Prominent 5d-orbital contribution to the conduction electrons in gold

A. Sekiyama, J. Yamaguchi, A. Higashiya +9

We have examined the valence-band electronic structures of gold and silver in the same column in the periodic table with nominally filled d orbitals by means of a recently develope…

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…

Charge dynamics in strongly correlated one-dimensional Cu-O chain systems revealed by inelastic X-ray scattering

S. Suga, S. Imada, A. Higashiya +11

We report on the Cu 1s resonant inelastic X-ray scattering (RIXS) of Cu-O one-dimensional (1D) strongly correlated insulator systems with contrasting atomic arrangements, namely ed…
