摘要：

We have used x-ray photoelectron spectroscopy to investigate the charge state of oxygen found in the basal structural plane of YBa2Cu 3O6+γ.. We have observed a change in this state after thermal treatment, with a transition to the adjacent structural phase region. We have shown that changes in the charge state of oxygen can be used as an indicator of structural changes occurring in YBa2Cu 3O6+δ.. We have found that the rate of structural relaxation yttrium barium cuprate depends on the amount of structural water it contains. © 2007 Springer Science+Business Media, Inc.
