Superconductivity at 52 K in hydrogen-substituted LaFeAsO1-xHx under high pressure

Hiroki Takahashi, Hideto Soeda, Muga Nukii +6

The 1111-type iron-based superconductor LnFeAsO1-xFx (Ln stands for lanthanide) is the first material with a Tc above 50 K, other than cuprate superconductors. Electron doping into…
