Plane dimpling and Cu 4s hybridization in YBa2Cu3Ox
Oxygen doping dimples the CuO2 planes of YBa2Cu3O6.8−6.92 by displacing copper normal to the planes and further towards Ba. The correlated oxygen displacements, however, are constrained to the in-plane axes. This displacement pattern is discussed in terms of doping dependent Cu 4s–3d hybridizations.

متن کاملPhotoinduced Changes of the In-Plane and Out-Of-Plane Electronic Properties in YBa2Cu3Ox
We report on the photoinduced changes of the electronic properties of YBa2Cu3Ox (x ≈ 6.6) thin films, focussing on the electrical anisotropy in the normal and the superconducting state. The latter was determined from magnetoconductivity measurements, performed before and after light excitation, and fitting the experimental results to the Aslamazov–Larkin theory of superconducting order-paramete...
متن کاملThe dimpling in the CuO2 planes of YBa2Cu3Ox (x=6.806-6.984, T=20-300 K) measured by yttrium EXAFS
The dimpling of the CuO2 planes (spacing between the O2,3 and Cu2 layers) in YBa2Cu3Ox has been measured as a function of oxygen concentration and temperature by yttrium x-ray extended-fine-structure spectroscopy (EXAFS). The relative variations of the dimpling with doping (x = 6.806 − 6.984) and temperature (20300 K) are weak (within 0.05 Å), and arise mainly from displacements of the Cu2 atom...
