Interplay of the electronic and lattice degrees of freedom in A_{1-x}Fe_{2-y}Se_{2} superconductors under pressure

M. Bendele, C. Marini, B. Joseph +12

The local structure and electronic properties of Rb${}_{1-x}$Fe${}_{2-y}$Se${}_2$ are investigated by means of site selective polarized x-ray absorption spectroscopy at the iron and sele…
