Correlation effects in CaCu3Ru4O12
N. Hollmann, Z. Hu, A. Maignan +7
We have investigated the electronic structure of CaCu3Ru4O12 and LaCu3Ru4O12 using soft x-ray photoelectron and absorption spectroscopy together with band structure and cluster con…
Local correlations, non-local screening, multiplets, and band formation in NiO
T. Haupricht, J. Weinen, A. Tanaka +17
We report on a comparative study of the valence band electronic structure of NiO as bulk material and of NiO as impurity in MgO. From the impurity we have been able to determine re…
Disorder-driven electronic localization and phase separation in superconducting Fe1+yTe0.5Se0.5 single crystals
S. Rößler, Dona Cherian, S. Harikrishnan +6
We have investigated the influence of Fe-excess on the electrical transport and magnetism of Fe1+yTe0.5Se0.5 (y=0.04 and 0.09) single crystals. Both compositions exhibit resistivel…
Crystal-field ground state of the orthorhombic Kondo insulator CeRu2Al10
F. Strigari, T. Willers, Y. Muro +11
We have succeeded in establishing the crystal-field ground state of CeRu2Al10, an orthorhombic intermetallic compound recently identified as a Kondo insulator. Using polarization d…
Mott versus Slater-type metal-insulator transition in Mn-substituted Sr3Ru2O7
M. A. Hossain, B. Bohnenbuck, Y. D. Chuang +15
We present a temperature-dependent x-ray absorption (XAS) and resonant elastic x-ray scattering (REXS) study of the metal-insulator transition (MIT) in Sr3(Ru1-xMnx)2O7. The XAS re…
Determining the in-plane orientation of the ground-state orbital of CeCu2Si2
T. Willers, F. Strigari, N. Hiraoka +9
We have successfully determined the hitherto unknown sign of the B44 Stevens crystal-field parameter of the tetragonal heavy-fermion compound CeCu2Si2 using vector q dependent non-…
