Orbital reflectometry
E. Benckiser, M. W. Haverkort, S. Brueck +13
The occupation of d-orbitals controls the magnitude and anisotropy of the inter-atomic electron transfer in transition metal oxides and hence exerts a key influence on their chemic…
Crossover from weak to strong pairing in unconventional superconductors
D. S. Inosov, J. T. Park, A. Charnukha +4
Superconductors are classified by their pairing mechanism and the coupling strength, measured as the ratio of the energy gap to the critical temperature, Tc. We present an extensiv…
Superconductivity-induced optical anomaly in an iron arsenide
A. Charnukha, P. Popovich, Y. Matiks +5
One of the central tenets of conventional theories of superconductivity, including most models proposed for the recently discovered iron-pnictide superconductors, is the notion tha…
Evidence of precursor superconductivity as high as 180 K from infrared spectroscopy
A. Dubroka, M. Roessle, K. W. Kim +13
We show that a multilayer analysis of the infrared c-axis response of RBa2Cu3O7-d (R=Y, Gd, Eu) provides important new information about the anomalous normal state properties of un…
Symmetry of spin excitation spectra in the tetragonal paramagnetic and superconducting phases of 122-ferropnictides
J. T. Park, D. S. Inosov, A. Yaresko +16
We study the symmetry of spin excitation spectra in 122-ferropnictide superconductors by comparing the results of first-principles calculations with inelastic neutron scattering (I…
Neutron scattering study of the magnetic phase diagram of underdoped YBa(2)Cu(3)O(6+x)
D. Haug, V. Hinkov, Y. Sidis +6
We present a neutron triple-axis and resonant spin-echo spectroscopy study of the spin correlations in untwinned YBCO crystals with x= 0.3, 0.35, and 0.45 as a function of temperat…
