الوصف: We have studied the electronic structure of EuFe2As2-xPx using high-resolution angle-resolved photoemission spectroscopy. Upon substituting As with the isovalent P, which leads to chemical pressure and to superconductivity, we observe a nonrigid-band-like change of the electronic structure along the center of the Brillouin zone (BZ) in the form of an orbital and kz-dependent increase or decrease in the size of the hole pockets near the Γ−Z line. The diameter of the Fermi surface cylinders at the BZ corner which form electron pockets, increases at K and changes in a nonmonotonous way at X. This is in stark contrast to p- and n-type doped iron pnictides where, on the basis of ARPES experiments, a more rigid-band-like behavior has been proposed. These findings indicate that there are different ways in which the nesting conditions can be reduced causing the destabilization of the antiferromagnetic order and the appearance of the superconducting dome.
