Scale-free structural organization of oxygen interstitials in La2CuO4+y
Michela Fratini, Nicola Poccia, Alessandro Ricci +4
It is well known that the microstructures of the transition-metal oxides (refs 1-3), including the high-transition-temperature (high-Tc) copper oxide superconductors (refs 4-7), ar…
Inelastic x-ray scattering investigations of lattice dynamics in SmFeAsOF superconductors
M. Le Tacon, T. R. Forrest, Ch. Rüegg +10
We report measurements of the phonon density of states as measured with inelastic x-ray scattering in SmFeAsOF powders. An unexpected strong renormalization of phonon b…
Electronic structure of superconducting KC and non-superconducting LiC graphite intercalation compounds: Evidence for a graphene-sheet-driven superconducting state
Z. -H. Pan, J. Camacho, M. H. Upton +4
We have performed photoemission studies of the electronic structure in LiC and KC, a non-superconducting and a superconducting graphite intercalation compound, respectively…
Field-induced soft-mode quantum phase transition in LaSrCuO
J. Chang, N. B. Christensen, Ch. Niedermayer +13
Inelastic neutron-scattering experiments on the high-temperature superconductor LaSrCuO reveal a magnetic excitation gap that decreases continuously u…
Thermal fluctuations in moderately damped Josephson junctions: Multiple escape and retrapping, switching- and return-current distributions and hysteresis
J. C. Fenton, P. A. Warburton
A crossover at a temperature T* in the temperature dependence of the width s of the distribution of switching currents of moderately damped Josephson junctions has been reported in…
Mechanism of phase transitions and the electronic density of states in (La,Sm)FeAsOF from ab initio calculations
P. V. Sushko, A. L. Shluger, M. Hirano +1
The structure and electronic density of states in layered LnFeAsOF (Ln=La,Sm; =0.0, 0.125, 0.25) are investigated using density functional theory. For the =0.0 sy…
