Observation of superconductivity at 30∼46K in A(x)Fe(2)Se(2 )(A = Li, Na, Ba, Sr, Ca, Yb, and Eu)
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 of superconductivity at about 30 K in KFe(2)Se(2), but all have failed so far. Here we demonstrate that a series of sup...
