Iron-Based Layered Superconductor La[O<sub>1-</sub><i><sub>x</sub></i>F<i><sub>x</sub></i>]FeAs (<i>x</i> = 0.05−0.12) with <i>T</i><sub>c</sub> = 26 K
We report that a layered iron-based compound LaOFeAs undergoes superconducting transition under doping with F- ions at the O2- site. The transition temperature (Tc) exhibits a t...
