Synthesis and Physical Properties of the New Potassium Iron Selenide Superconductor K0.80Fe1.76Se2
LaFeO1−xFx with Tc = 26 K was reported in early 2008. Since then, more than 4,000 papers have been published and the maximumTc reached 56 K, which is next to high-Tc cuprates. Iron-based superconductors have several unique propertiesmostly arising fromtheir multi-orbital nature. The presence of a vast number of parentmaterials …
