Transport properties and superconductivity in KLnFeAs (Ln=Sm, Nd and La) system
R. H. Liu, G. Wu, H. Chen +8
We prepared the samples KLnFeAs (Ln=Sm, Nd and La) with ThCrSi-type structure. These samples were characterized by X-ray diffraction, resistivity, sus…
Doping-Driven Collapse of the SDW Correlation Gap in SmFeAsOF
Scott C. Riggs, R. D. McDonald, J. B. Kemper +8
We report the Hall resistivity, of polycrystalline SmFeAsOF for four different fluorine concentrations from the onset of superconductivity through the collap…
Log-T divergence and Insulator-to-Metal Crossover in the normal state resistivity of fluorine doped SmFeAsO1-xFx
S. C. Riggs, J. B. Kemper, Y. Jo +8
We report the resistivity of a series of fluorine-doped SmFeAsO1-xFx polycrystalline superconductors in magnetic fields up to 60T. For underdoped samples (x < 0.15), the low temper…
Far-infrared probe of superconductivity in SmOFFeAs}
S. I. Mirzaei, V. Guritanu, A. B. Kuzmenko +5
We report far-infrared reflectance measurements on polycrystalline superconducting samples of SmOFFeAs ( = 0.12, 0.15 and 0.2). We clearly observe superconductivit…
Superconducting Gap and Pseudogap in Sm(OF)FeAs Layered Superconductor from Photoemission Spectroscopy
Haiyun Liu, Xiaowen Jia, Wentao Zhang +20
High resolution photoemission measurements have been carried out on non-superconducting SmOFeAs parent compound and superconducting Sm(OF)FeAs (x=0.12, and 0.15) compou…
Neutron scattering study of the oxypnictide superconductor La(O,F)FeAs
Y. Qiu, M. Kofu, Wei Bao +8
The newly discovered superconductor La(O,F)FeAs (Tc = 26 K) was investigated using the neutron scattering technique. No spin-density-wave (SDW) order was observed in the normal sta…
