Universal electronic structure of multi-layered nickelates via oxygen-centered planar orbitals
Christine C. Au-Yeung, X. Chen, S. Smit +17
Superconductivity has been demonstrated in the family of multi-layered nickelates LaNiO and LaNiO. Key questions remain open regarding the low-energy ele…
Systematics of c-axis Phonons in the Thallium and Bismuth Based Cuprate Superconductors
A. A. Tsvetkov, D. Dulic, D. van der Marel +9
We present grazing incidence reflectivity measurements in the far infrared region at temperatures above and below Tc for a series of thallium (Tl2Ba2CuO6, Tl2Ba2CaCu2O8) and bismut…
Optical spectroscopy of pure and doped CuGeO3
A. Damascelli, D. van der Marel, G. Dhalenne +1
We investigated in detail the optical properties of several Cu(1-delta)Mg(delta)GeO3 (with delta=0,0.01), and CuGe(1-x)B(x)O3 with B=Si (x=0,0.007,0.05,0.1), and Al (x=0,0.01) sing…
Optical spectroscopic study of the interplay of spin and charge in NaV2O5
A. Damascelli, C. Presura, D. van der Marel +2
We investigate the temperature dependent optical properties of NaV2O5, in the energy range 4meV-4eV. The symmetry of the system is discussed on the basis of infrared phonon spectra…
Charged Magnons in NaV2O5
A. Damascelli, D. van der Marel, M. Grueninger +4
We investigated the temperature-dependent optical conductivity of NaV2O5 in the energy range 4 meV-4 eV. The intensities and the polarization dependence of the detected electronic…
Infrared signatures of the spin-Peierls transition in CuGeO3
A. Damascelli, D. van der Marel, F. Parmigiani +2
We investigated the infrared reflectivity of several Mg- and Si-substituted CuGeO3 single crystals. The temperature dependent b-axis and c-axis optical response is reported. For T<…
