Systematic investigation of a family of gradient-dependent functionals for solids
Philipp Haas, Fabien Tran, Peter Blaha +4
Eleven density functionals are compared with regard to their performance for the lattice constants of solids. We consider standard functionals, such as the local-density approximat…
Magneto-optic far-infrared study of SrCuO: triplet excitations in chains
D. Hüvonen, U. Nagel, T. Rõõm +4
Using far-infrared spectroscopy we have studied the magnetic field and temperature dependence of the spin gap modes in the chains of SrCuO. Two triplet modes T…
Electronic and vibrational properties of low-dimensional perovskites SrLaNbO
C. A. Kuntscher, S. Schuppler, P. Haas +4
By angle-resolved photoemission spectroscopy and polarization-dependent infrared reflectivity measurements the electronic and vibrational properties of low-dimensional perovskites…
Anisotropic Charge Modulation in Ladder Planes of Sr_14-xCa_xCu_24O_41
T. Vuletic, T. Ivek, B. Korin-Hamzic +7
The charge response of the ladders in Sr_14-xCa_xCu_24O_41 is characterized by dc resistivity, low frequency dielectric and optical spectroscopy in all three crystallographic direc…
Suppression of the charge-density-wave state in Sr_14Cu_24O_41 by calcium doping
T. Vuletic, B. Korin-Hamzic, S. Tomic +7
The charge response in the spin chain/ladder compound Sr_14-xCa_xCu_24O_41 is characterized by DC resistivity, low-frequency dielectric spectroscopy and optical spectroscopy. We id…
Variable-range hopping conductivity in the copper-oxygen chains of La_3Sr_3Ca_8Cu_24O_41
T. Vuletic, B. Korin-Hamzic, S. Tomic +6
We show that the spin chain/ladder compound La_3Sr_3Ca_8Cu_24O_41 is an insulator with hopping transport along the chains. In the temperature range 35 - 280 K, DC conductivity sigm…
