Superconductivity at 52 K in iron based F doped layered quaternary compound Pr[O<sub>1–x</sub>F<sub>x</sub>]FeAs
AbstractHere the authors report that by a high pressure synthesis method, superconductivity with an onset transition temperature at 52 K was discovered in a fluorine-doped quaternary iron-arsenide compound Pr[O1-xFx]FeAs, with the zero resistivity and Meissner transition appeared at 44 K and 50 K respectively. As the first non-cuprate compound that …
