Momentum dependence of the superconducting gap in BaKFeAs
D. V. Evtushinsky, D. S. Inosov, V. B. Zabolotnyy +12
The precise momentum dependence of the superconducting gap in the iron-arsenide superconductor with Tc = 32K (BKFA) was determined from angle-resolved photoemission spectroscopy (A…
(pi,pi)-electronic order in iron arsenide superconductors
V. B. Zabolotnyy, D. S. Inosov, D. V. Evtushinsky +14
The distribution of valence electrons in metals usually follows the symmetry of an ionic lattice. Modulations of this distribution often occur when those electrons are not stable w…
On the electronic structure of electron doped LaOFeAs as seen by X-ray absorption spectroscopy
T. Kroll, S. Bonhommeau, T. Kachel +14
We investigated the recently found superconductor LaO_{1-x}F_xFeAs by X-ray absorption spectroscopy (XAS). From a comparison of the O K-edge with LDA calculations we find good agre…
Valence band and core level photoemission spectros-copy of LaFeAsOF
A. Koitzsch, D. Inosov, J. Fink +9
We have investigated the electronic structure of LaFeAsOF (x = 0; 0.1; 0.2) by angle-integrated photoemission spectroscopy and local density approximation (LDA) based…
High-Field Pauli-Limiting Behavior and Strongly Enhanced Upper Critical Magnetic Fields near the Transition Temperature of an Arsenic-Deficient LaO_0.9F_0.1FeAs_(1-δ) Superconductor
G. Fuchs, S. -L. Drechsler, N. Kozlova +14
We report upper critical field B_c2(T) data for disordered (arsenic-deficient) LaO_0.9F_0.1FeAs_(1-delta) in a wide temperature and magnetic field range up to 47 T. Because of the…
Optical Study of LaO_0.9F_0.1FeAs: Evidence for a Weakly Coupled Superconducting State
S. -L. Drechsler, M. Grobosch, K. Koepernik +10
We have studied the reflectance of the recently discovered superconductor LaO_0.9F0.FeAs in a wide energy range from the far infrared to the visible regime. We report on the observ…
