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…
Fabrication and some properties of biaxially aligned Sr0.6K0.4Fe2As2 superconductors by processing in high magnetic field
Zhaoshun Gao, Xianping Zhang, Dongliang Wang +7
We fabricated the c axis and ab-plane biaxially aligned Sr0.6K0.4Fe2As2 superconductor using a two-step magnetic field procedure. The effect of magnetic fields on the structure and…
Superconductivity in Ir-doped LaFe1-xIrxAsO
Yanpeng Qi, Lei Wang, Zhaoshun Gao +4
We report the realization of superconductivity by 5d element Ir doping in LaFeAsO, a prototype parent compound of high-temperature iron based superconductors. X-ray diffraction pat…
Superconductivity in Co-doped SmFeAsO
Yanpeng Qi, Zhaoshun Gao, Lei Wang +3
Here we report the synthesis and basic characterization of SmFe1-xCoxAsO (x=0.10, 0.15). The parent compound SmFeAsO itself is not superconducting but shows an antiferromagnetic or…
Structural and critical current properties in polycrystalline SmO1-xFxFeAs
Lei Wang, Zhaoshun Gao, Yanpeng Qi +3
A series of polycrystalline SmO1-xFxFeAs bulks (x=0.15, 0.2, 0.3 and 0.4) were prepared by the conventional solid state reaction. Resistivity, susceptibility, magnetic hysteresis,…
Superconductivity at 34.7 K in the iron arsenide Eu0.7Na0.3Fe2As2
Yanpeng Qi, Zhaoshun Gao, Lei Wang +3
EuFe2As2 is a member of the ternary iron arsenide family. Similar to BaFe2As2 and SrFe2As2, EuFe2As2 exhibits a clear anomaly in resistivity near 200 K. It suggests that EuFe2As2 i…
