Electronic signature of the vacancy ordering in NbO (Nb3O3)
A. K. Efimenko, N. Hollmann, K. Hoefer +15
We investigated the electronic structure of the vacancy-ordered 4d-transition metal monoxide NbO (Nb3O3) using angle-integrated soft- and hard-x-ray photoelectron spectroscopy as w…
Dynamic atomic reconstruction: how Fe3O4 thin films evade polar catastrophe for epitaxy
C. F. Chang, Z. Hu, S. Klein +10
Polar catastrophe at the interface of oxide materials with strongly correlated electrons has triggered a flurry of new research activities. The expectations are that the design of…
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…
Insulator-Metal Transition in TiGePt: a combined photoelectron spectroscopy, x-ray absorption spectroscopy, and band structure study
J. Gegner, M. Gamza, S. -V. Ackerbauer +10
We present a combined experimental and theoretical study of the electronic structure of the intermetallic compound TiGePt by means of photoelectron spectroscopy, x-ray absorption s…
Local electronic structure of Fe impurities in MgO thin films: Temperature-dependent soft x-ray absorption spectroscopy study
T. Haupricht, R. Sutarto, M. W. Haverkort +7
We report on the local electronic structure of Fe impurities in MgO thin films. Using soft x-ray absorption spectroscopy (XAS) we verified that the Fe impurities are all in the 2+…
Local symmetry and magnetic anisotropy in multiferroic MnWO4 and antiferromagnetic CoWO4 studied by soft x-ray absorption spectroscopy
N. Hollmann, Z. Hu, T. Willers +7
Soft x-ray absorption experiments on the transition metal L2,3 edge of multiferroic MnWO4 and antiferromagnetic CoWO4 are presented. The observed linear polarization dependence, an…
