Suppression of by Zn impurity in the electron-type LaFeCoZnAsO system
Yuke Li, Jun Tong, Qian Tao +2
The effect of non-magnetic Zn impurity on superconductivity in electron-type pnictide superconductor LaFeCoZnAsO is studied systematically. The optimally…
Superconductivity in LaFeAsPO: effect of chemical pressures and bond covalency
Cao Wang, Shuai Jiang, Qian Tao +7
We report the realization of superconductivity by an isovalent doping with phosphorus in LaFeAsO. X-ray diffraction shows that, with the partial substitution of P for As, the Fe$_2…
Superconductivity induced by Ni doping in BaFeAs
L. J. Li, Q. B. Wang, Y. K. Luo +8
A series of 122 phase BaFeNiAs ( = 0, 0.055, 0.096, 0.18, 0.23) single crystals were grown by self flux method and a dome-like Ni doping dependence of supercondu…
Effect of Zn doping on magnetic order and superconductivity in LaFeAsO
Yuke Li, Xiao Lin, Qian Tao +7
We report Zn-doping effect in the parent and F-doped LaFeAsO oxy-arsenides. Slight Zn doping in LaFeZnAsO drastically suppresses the resistivity anomaly around 150 K…
Narrow superconducting window in Ni-doped LaFeAsO
Guanghan Cao, Shuai Jiang, Xiao Lin +7
We have studied Ni-substitution effect in LaFeNiAsO () by the measurements of x-ray diffraction, electrical resistivity, magnetic susceptibility, and…
Thorium-doping induced superconductivity up to 56 K in Gd1-xThxFeAsO
Cao Wang, Linjun Li, Shun Chi +10
Following the discovery of superconductivity in an iron-based arsenide LaO1-xFxFeAs with a superconducting transition temperature (Tc) of 26 K[1], Tc was pushed up surprisingly to…
