The dependence of the internal friction and Young's modulus on the oxygen deficiency in the superconductor YBa: Cu 3 07\_ ~ was studied at frequencies near 2. 7 kHz. Peaks observed near 110 and 230 K decreased with decreasing oxygen stoichiometry in a sample with the orthorhombic structure, and were
A polarised X-ray absorption study is made on an underdoped YBCO substantially detwinned single crystal to study the anomalous temperature dependence of itinerant holes, charge aggregation and pair formation along the Ekb and Eka directions. The measurements were made at the O K and Cu L 3 edges var
