Tunable Cobalt Vacancies and Related Properties in LaCoxAs2
Shijie Shen, Gang Wang, Shifeng Jin +9
The origin of transition metal vacancies and their effects on the properties of ThCr2Si2-type compounds have been less studied and poorly understood. Here we carefully investigate…
Superconducting Phases in Potassium-Intercalated Iron Selenides
Tianping Ying, Xiaolong Chen, Gang Wang +6
The ubiquitous coexistence of majority insulating 245 phases and minority superconducting (SC) phases in AxFe2-ySe2 (A = K, Cs, Rb, Tl/Rb, Tl/K) formed by high-temperature routes m…
Observation of superconductivity at 30 K~46 K in AxFe2Se2 (A = Li, Na, Ba, Sr, Ca, Yb, and Eu)
T. P. Ying, X. L. Chen, G. Wang +5
New iron selenide superconductors by intercalating smaller-sized alkali metals (Li, Na) and alkaline earths using high-temperature routes have been pursued ever since the discovery…
Quenching of superconductivity by Co doping in K0.8Fe2Se2
Tingting Zhou, Xiaolong Chen, Jiangang Guo +5
We synthesized a series of K0.8Fe2-xCoxSe2 samples with nominal compositions 0\leq x\leq 0.035 and investigated their physical properties. The results show that the superconductivi…
Superconductivity on the verge of Mott localization in ternary iron sulfide
Jiangang Guo, Xiaolong Chen, Gang Wang +5
We report the results of electrical and magnetic properties on two new compounds, K0.8Fe1.7S2 and K0.8Fe1.7SeS, both having similar structures to newly discovered superconducting K…
Superconductivity in the iron selenide KxFe2Se2 (0 <= x <= 1)
Jiangang Guo, Shifeng Jin, Gang Wang +5
We report the superconductivity at above 30 K in a new FeSe-layer compound K0.8Fe2Se2 (nominal composition) achieved by metal K intercalating in between FeSe layers. It is isostruc…
