High-energy x-ray diffraction is used to investigate the bulk oxygen-ordering properties of
YBa 2 Cu 3 O 6+ x. Four different superstructures of Cu-O chains aligned along the b axis …

Strong electronic nanoscale disorder is present in all cuprate high-temperature
superconductors, interwoven with the microscopic mechanisms responsible for both the high …

Oxygen vacancies are introduced in the RuO 2 and possibly CuO 2 planes of RuSr 2 GdCu
2 O 8 by annealing in vacuum above 600 K. The diffusive jumps of the O vacancies are …

The superconducting properties of YBa 2 Cu 3 O 7-δ (YBCO) are strongly dependent on
atomic structure and composition. While the average structures of YBCO are well …

We investigated the time and temperature dependence of photobleaching effects in R Ba 2
Cu 3 O 7− δ single crystals (R= Y, Pr) by Raman spectroscopy and Monte Carlo simulations …

During systematic studies of the structural phase diagram of YBa 2 Cu 3 O 6+ x (YBCO), a
YBCO single crystal of oxygen concentration x= 0.62 turned out to have a tetragonal crystal …

By means of ab initio calculations within the local density approximation to density functional
theory, we investigate the electronic structure of the 60 K superconductor YSr 2 Cu 3 O 6+ x …

Diffuse scattering from a crystal contains valuable information about the two‐body
correlations (related to the nanoscale order) in the material. Despite years of development …

The influence of oxygen ordering on the Meissner fraction (the ratio of field cooled to zero
field cooled magnetization) on a number of YBa 2 Cu 3 O 7− δ single crystals over a wide …

YBCO, LSCO and Ru-1212 have been extensively studied by measuring the complex
dynamic Young's modulus at 0.5-20 kHz between 1 and 900 K. The elastic energy loss is …
