Fermi Surface and Band Renormalization in (Sr,K)FeAs Superconductor from Angle-Resolved Photoemission Spectroscopy
Haiyun Liu, Wentao Zhang, Lin Zhao +16
High resolution angle-resolved photoemission measurements have been carried out on (Sr,K)FeAs superconductor (Tc=21 K). Three hole-like Fermi surface sheets are clearly res…
Point contact Andreev reflection spectroscopy of NdFeAsO_0.85
K A Yates, L F Cohen, Zhi-An Ren +4
The newly discovered oxypnictide family of superconductors show very high critical temperatures of up to 55K. Whilst there is growing evidence that suggests a nodal order parameter…
Evidence for two distinct scales of current flow in polycrystalline Sm and Nd iron oxypnictides
A. Yamamoto, A. A. Polyanskii, J. Jiang +13
Early studies have found quasi-reversible magnetization curves in polycrystalline bulk rare-earth iron oxypnictides that suggest either wide-spread obstacles to intergranular curre…
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…
The effect of internal pressure on the tetragonal to monoclinic structural phase transition in ReOFeAs: the case of NdOFeAs
Michela Fratini, Rocchina Caivano, Alessandro Puri +10
We report the temperature dependent x-ray powder diffraction of the quaternary compound NdOFeAs (also called NdFeAsO) in the range between 300 K and 95 K. We have detected the stru…
Superconductivity at 41.0 K in the F-doped LaFeAsO1-xFx
Wei Lu, Xiao-Li Shen, Jie Yang +8
Here we report the superconductivity in the LaFeAsO1-xFx system prepared by high pressure synthesis. The highest onset superconducting transition temperature (Tc) in this La-based…
