Importance of $${{d}}_{{{xy}}}$$ d xy orbital and electron correlation in iron-based superconductors revealed by phase diagram for 1111-system

Abstract The structural flexibility at three substitution sites in LaFeAsO enabled investigation of the relation between superconductivity and structural parameters over a wide range of crystal compositions. Substitutions of Nd for La, Sb or P for As, and F or H for O were performed. All these subst...
