Abstract

Iron arsenide superconductors based on the material LaFeAsO1−xFx are characterized by a two-dimensional Fermi surface (FS) consisting of hole and electron pockets yielding structural and antiferromagnetic transitions at x=0. Electron doping by substituting O2− with F− suppresses these transitions and gives rise to superconductivity with a maximum Tc of 26 K at x=0.1. However, the over-doped region cannot be accessed due to the poor solubility of F− above x=0.2. Here we overcome this problem by doping LaFeAsO with hydrogen. We report the phase diagram of LaFeAsO1−xHx (x
