Heat treatment effects on the superconducting properties of Ag-doped SrKFeAs compound
Zhiyu Zhang, Lei Wang, Yanpeng Qi +4
The superconducting properties of polycrystalline Sr0.6K0.4Fe2As2 were strongly influenced by Ag doping (Supercond. Sci. Technol. 23 (2010) 025027). Ag addition is mainly dominated…
Low-temperature synthesis of SmO0.8F0.2FeAs superconductor with Tc = 56.1K
Chunlei Wang, Zhaoshun Gao, Lei Wang +5
We report a systematic study on the effect of sintering temperature on the structural and superconducting properties of nominal SmO0.8F0.2FeAs fabricated by simple one-step solid s…
Low-temperature synthesis of SmFeAsO0.7F0.3 wires with high transport critical current density
Lei Wang, Yanpeng Qi, Dongliang Wang +5
Ag-sheathed SmFeAsO0.7F0.3 (Sm-1111) superconducting wires were prepared by a one-step solid state reaction at temperatures as low as 850~900C, instead of commonly used temperature…
Influence of Pb addition on the superconducting properties of polycrystalline Sr0.6K0.4Fe2As2
Lei Wang, Yanpeng Qi, Zhiyu Zhang +5
Polycrystalline Sr0.6K0.4Fe2As2 samples with various Pb additions (0-20 wt%) were prepared using a one-step solid state reaction. X-ray diffraction analysis shows no evidence for c…
CO observations of SNR IC 443
Zhiyu Zhang, Yu Gao, Junzhi Wang
We present our 12CO and 13CO mapping observations of SNR IC 443, interacting with molecular clouds. It is the first large scale high resolution 13CO mapping observation in the surr…
Large transport critical currents of powder-in-tube Sr0.6K0.4Fe2As2/Ag superconducting wires and tapes
Lei Wang, Yanpeng Qi, Dongliang Wang +7
We report significant transport critical currents firstly achieved in Sr0.6K0.4Fe2As2 wires and tapes with a Tc = 34 K, which were fabricated through an in-situ powder-in-tube proc…
