“…We see from Fig. 16.21 that the CuO 6 octahedra have now lost their apical oxygens, (Alp et al, 1989;Barlingay et al, 1990;Ekino and Akimitsu, 1989a,b;Lederman et al, 1991;Luke et al, 1990;Sugiyama et al, 1991. Other rare earths, such as Pr (Lee et al, 1990) and Sm (Almasan et al, 1992) have replaced Nd.…”

“…The same 2-3% of Zn in place of Cu in the CuO 2 planes destroys SC at optimal doping both in hole-doped LSCO [6] and in electron-doped NCCO [7]. No structural change is involved, hence the effect is a local electronic probe into the SC mechanism.…”

The role of the oxygen degree of freedom in the cuprates' superconducting planes is analyzed in detail. Structural and photoemission results are reviewed to show that the most sparse description of the in-plane electronic states requires explicit control of the oxygens. For metallic states, the relative contributions of oxygen and copper vary along the Fermi surface (FS), with the arc metallicity dominantly oxygen-derived. For the magnetic responses, we find that the observed incommensurability arises naturally if one keeps separate the roles of the two sites. For the charge order in LBCO, we propose a scenario, based on magnetic interactions in the plane. We stress the need for further experimental investigations of the evolution of the intracell charge distribution with doping, and for a better theoretical understanding of the large particle-hole-symmetry breaking required for successful phenomenologies, but difficult to reconcile with ab initio calculations.

“…In this context, it is notable that in cuprates, both hole and electron doping induce hole conductivity. [6,31] Atomic The calculated ionicities are given in Table 1. Atomic charges were estimated by standard Mulliken population analysis [32].…”

“…They functionalize by metallization against an ionic background. In the cuprates, the metallization is based on hole-doped oxygen orbitals [3][4][5][6]. In the pnictides, it is due to the Fe t2g orbitals.…”
