Anomalies in the Fermi surface and band dispersion of quasi-one-dimensional CuO chains in the high-temperature superconductor YBa2Cu4O8
Takeshi Kondo, R. Khasanov, J. Karpinski +12
We have investigated the electronic states in quasi one dimensional (1D) CuO chains by microprobe Angle Resolved Photoemission Spectroscopy. We find that the quasiparticle Fermi su…
Strong coupling between Eu2+ spins and Fe2As2 layers in EuFe1.9Co0.1As2 observed with NMR
Z. Guguchia, J. Roos, A. Shengelaya +8
A combination of x-ray diffraction, magnetization, and 75As nuclear magnetic resonance (NMR) experiments were performed on single-crystal EuFe1.9Co0.1As2. The strength of the hyper…
Fermi-surface of underdoped LaFeAsO1-xFx as determined by the Haas-van Alphen-effect
G. Li, B. S. Conner, S. Weyeneth +7
Here, we present a de Haas-van Alphen (dHvA) effect1 study on the newly discovered LaFeAsO1-xFx compounds2,3 in order to unveil the topography of the Fermi surface associated with…
Local quasiparticle density of states of superconducting SmFeAsOF single crystals: Evidence for spin-mediated pairing
Y. Fasano, I. Maggio-Aprile, N. D. Zhigadlo +3
We probe the local quasiparticles density-of-states in micron-sized SmFeAsOF single-crystals by means of Scanning Tunnelling Spectroscopy. Spectral features resemble…
Structural phase transition and superlattice misfit strain of RFeAsO (R = La, Pr, Nd and Sm)
Alessandro Ricci, Nicola Poccia, B. Joseph +9
The tetragonal-to-orthorhombic structural phase transition (SPT) in LaFeAsO (La-1111) and SmFeAsO (Sm-1111) single crystals measured by high resolution x-ray diffraction is found t…
Th substituted SmFeAsO: structural details and superconductivity with Tc above 50 K
N. D. Zhigadlo, S. Katrych, S. Weyeneth +6
Superconducting poly- and single-crystalline samples of Sm1-xThxFeAsO with partial substitution of Sm3+ by Th4+ were synthesized and grown under high pressure and their structural,…
