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…
A cheap liquid additive from acetone for strong in-field Jc enhancement in MgB2 conductors
Dongliang Wang, Yanwei Ma, Zhaoshun Gao +5
We report on significant flux pinning enhancement in MgB2/Fe tapes that has been easily obtained by a simple and cheap route using acetone as both an efficient ball-milling medium…
Superconducting properties of SmO1-xFxFeAs wires with Tc = 52 K prepared by the powder-in-tube method
Zhaoshun Gao, Lei Wang, Yanpeng Qi +5
We demonstrate that Ta sheathed SmO1-xFxFeAs wires were successfully fabricated by the powder-in-tube (PIT) method for the first time. Structural analysis by mean of x-ray diffract…
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…
