New Superconductivity Dome in LaFeAsO${}_{1-x}$F${}_x$ Accompanied by Structural Transition

J. Yang, R. Zhou, L. L. Wei +4

High temperature superconductivity is often found in the vicinity of antiferromagnetism. This is also true in LaFeAsO${}_{1-x}$F${}_x$ ($x\le$ 0.2) and many other iron-based superc…
