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…
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…
One step synthesis of SmO1-xFxFeAs bulks with Tc = 54.6 K: High upper critical field and critical current density
Yanwei Ma, Zhaoshun Gao, Lei Wang +3
A safe, simple and easily scaleable one-step sintering method is proposed to fabricate newly discovered superconductors of SmO1-xFxFeAs. Superconducting transition with the onset t…
