High transport critical current densities in textured Fe-sheathed Sr1-xKxFe2As2+Sn superconducting tapes
Zhaoshun Gao, Lei Wang, Chao Yao +6
We report the realization of grain alignment in Sn-added Sr1-xKxFe2As2 superconducting tapes prepared by ex-situ powder-in-tube method. At 4.2 K, high transport critical current de…
Transport properties and anisotropy in rare earth doped CaFe2As2 single crystals with Tc above 40 K
Yanpeng Qi, Zhaoshun Gao, Lei Wang +6
In this paper we report the superconductivity above 40 K in the electron doping single crystal Ca1-xRexFe2As2 (Re = La, Ce, Pr). The x-ray diffraction patterns indicate high crysta…
Synthesis and properties of La-doped CaFe2As2 single crystals with Tc = 42.7 K
Zhaoshun Gao, Yanpeng Qi, Lei Wang +5
Large single crystals of La-doped CaFe2As2 were successfully synthesized by the FeAs self-flux method. The x-ray diffraction patterns suggest high crystalline quality and c-axis or…
Direct observation of nanometer-scale amorphous layers and oxide crystallites at grain boundaries in polycrystalline Sr1-xKxFe2As2 superconductors
Lei Wang, Yanwei Ma, Qingxiao Wang +8
We report here an atomic resolution study of the structure and composition of the grain boundaries in polycrystalline Sr0.6K0.4Fe2As2 superconductor. A large fraction of grain boun…
Superconducting properties of FeSe wires and tapes prepared by gas diffusion technique
Zhaoshun Gao, Yanpeng Qi, Lei Wang +4
Superconducting FeSe in the form of wires and tapes were successfully fabricated using a novel gas diffusion procedure. Structural analysis by mean of x-ray diffraction shows that…
Upper fields and critical current density of K0.58Fe1.56Se2 single crystals grown by one step technique
Zhaoshun Gao, Yanpeng Qi, Lei Wang +4
Single crystals of K0.58Fe1.56Se2 were successfully synthesized by a new single step process with the onset superconducting transition temperatures 31.9 K. The x-ray diffraction pa…
