Defect Structure of YBa2Cu3O7-δ
Abstract
From the analysis of NQR spectra for Cu and on the basis of investigations of high-temperature electrical conductivity and thermal e.m.f. depending on oxygen pressure and temperature it is shown that in YBa2Cu3O7-δ there are pair correlations of the oxygen atoms which lead to formation of the (O2)z- pairs, the charge of which is determined by deviation from stoichiometry.
