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…
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…
Superconductivity of powder-in-tube LaO0.9F0.1FeAs wires
Zhaoshun Gao, Lei Wang, Yanpeng Qi +3
We demonstrate that Fe sheathed LaO0.9F0.1FeAs wires with Ti as a buffer layer were successfully fabricated by the powder-in-tube (PIT) method. Comparing to the common two-step vac…
Strongly enhanced critical current density in Fe-sheathed MgB2 tapes by stearic acid and stearate doping
Zhaoshun Gao, Yanwei Ma, Xianping Zhang +6
Fe-sheathed MgB2 tapes with cheap stearic acid, Mg stearate and Zn stearate doping were prepared through the in situ powder-in-tube method. It is found that Jc, Hirr, and Hc2 were…
