We have carried out experimental and theoretical studies of the unoccupied electronic structure of ${\mathrm{Sr}}_{2}{\mathrm{CuO}}_{3},$ which can be regarded as the best realization of a one-dimensional model system containing cuprate chains. In th

We have investigated the unoccupied electronic structure of quasi-one-dimensional ${\mathrm{Li}}_{2}{\mathrm{CuO}}_{2}$ using polarization-dependent x-ray absorption spectroscopy. Although an isotropic ``in-plane'' situation is expected for the O $1s

The unoccupied electronic structure of the layered cuprates ${\mathrm{Sr}}_{2}{\mathrm{CuO}}_{2}{\mathrm{Cl}}_{2}$ and ${\mathrm{Ba}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{4}{\mathrm{Cl}}_{2}$ has been studied using polarization-dependent x-ray absorptio

The dielectric function of the quarternary superconductor YNi2B2C has been derived in an energy range from WmeV up to 50eV by linking together optical reflectance and electron energy loss measurements, obtained from polycrystalline samples at room te

Substituting Y in orthorhombic (Y,RE)Ba2Cu3O7 by any rare-earth element RE has generally little effect on the superconducting properties. For RE = Pr, however, superconductivity is completely suppressed. To elucidate this effect we have studied the u

High-energy electron energy-loss spectroscopy in transmission has been applied to obtain the absorption spectra at the B 1s, C 1s and Ni 2 p 3 2 excitation edges of bulk polycrystalline YNi2B2C. We find a close similarity in the near-edge structures

We have performed reflectance and EELS measurements on the quaternary superconductor YNi2B2C. Linking together the results of these two types of experiments we derived the dielectric function in the energy range between 10 meV and 50 eV. The data wer

Valence level photoemission measurements of the normal-state electronic structure of the new boro-carbide intermetallic superconductor YNi2B2C are presented. The behaviour of the Ni-dominated valence band peak at 1.4 eV binding energy and the states

The unoccupied electronic structure of ${\mathrm{SrCuO}}_{2}$ single crystals has been studied using x-ray-absorption spectroscopy. By choosing the orientation of the single crystals with respect to the polarization vector of the synchrotron radiatio
