High-field electron spin resonance spectroscopy study of GdOFFeAs superconductors
A. Alfonsov, F. Murányi, V. Kataev +16
We report a detailed investigation of GdOFFeAs (x = 0, 0.07 and 0.14) samples by means of high-field/high-frequency electron spin resonance (HF-ESR) together with mea…
WDX-Analysis of the New Superconductors RO(1-x)F(x)FeAs and Its Consequences on the Electronic Phase Diagram
Anke Köhler, Günter Behr
Polycrystalline samples of RO1-xFxFeAs (0 < x < 0.25) (R = La, Sm, Gd) were investigated by wavelength-dispersive X-ray spectroscopy (WDX) in the electron microscope to determine t…
Synthesis and physical properties of
Agnieszka Kondrat, Jorge Enrique Hamann-Borrero, Norman Leps +9
We have prepared the newly discovered Fe-based superconducting material () in polycrystalline form and have investigated the samples by mean…
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…
Field and Temperature Dependence of the Superfluid Density in LaO_{1-x}F_xFeAs Superconductors: A Muon Spin Relaxation Study
H. Luetkens, H. -H. Klauss, R. Khasanov +10
We present zero field and transverse field \muSR experiments on the recently discovered electron doped Fe-based superconductor LaO_{1-x}F_xFeAs. The zero field experiments on under…
