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…
Superconductivity at 53.5 K in GdFeAsO1-delta
Jie Yang, Zheng-Cai Li, Wei Lu +8
Here we report the fabrication and superconductivity of the iron-based arsenic-oxide GdFeAsO1-delta compound with oxygen-deficiency, which has an onset resistivity transition tempe…
Superconductivity at 55 K in iron-based F-doped layered quaternary compound Sm[O1-xFx]FeAs
Zhi-An Ren, Wei Lu, Jie Yang +8
Here we report the superconductivity in the iron-based oxyarsenide Sm[O1-xFx]FeAs, with the onset resistivity transition temperature at 55.0 K and Meissner transition at 54.6 K. Th…
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…
Superconductivity at 52 K in iron-based F-doped layered quaternary compound Pr[O1-xFx]FeAs
Zhi-An Ren, Jie Yang, Wei Lu +5
Since the discovery of copper oxide superconductor in 1986 [1], extensive efforts have been devoted to the search of new high-Tc superconducting materials, especially high-Tc syste…
