The electronic structure of the CuO 2 planes and CuO 3 chains in single-domain crystals of
YBa 2 Cu 3 O x has been investigated as a function of oxygen concentration (6≤ x≤ 7) …

Synchrotron x-ray diffraction measurements on a high purity single crystal reveal that the
absence of long-range ortho-II order in YB a 2 C u 3 O 6+ x is most likely due to random-field …

We present measurements or Ortho-III phase correlations in an untwinned single crystal of
YBa2Cu3O6. 77 by neutron scattering and the novel method of hard (95 keV) X-ray …

A lattice-gas model for the high-temperature oxygen-ordering thermodynamics in YBa 2 Cu
3 O 6+ x is presented, which assumes constant effective pair interactions between oxygen …

Recently, several kinds of photoinduced effects on superconducting properties of YBa 2 Cu
3 O y at low temperatures have been reported. Particularly, in the sample at the boundary of …

The dependence of the superconducting properties of YBa2Cu3O6+ y on the oxygen
content y is discussed in terms of a two-phase model in which it is assumed that the optimal …

The oxygen order in YBa 2 Cu 3 O 6+ x has been investigated by Monte Carlo simulation
with the two-dimensional anisotropic next-nearest-neighbor lattice gas model, the ASYNNNI …

Magnetic measurements have been used to evaluate the critical current density J c for YBa 2
Cu 3 O x samples with various oxygen content (x) and, for partially oxygenated samples (x …

Using computer simulation on a model of oxygen ordering in the basal Cu 1− y M y O x
plane of the high-temperature superconductor YBa 2 Cu 3− y M y O 6+ x, we show that the …

O K-edge x-ray-absorption near-edge-structure (XANES) spectra of (Nd 1− x Pr x) 1.05 Ba
1.95 Cu 3 O 7 for x= 0–0.5 and Nd 1.05 (Ba 1− z Pr z) 1.95 Cu 3 O 7+ δ for z= 0–0.25 were …
