Abstract

The oxygen-defect-induced phase transition from nonergodic to ergodic state in superconductors with intragrain granularity is considered within the superconductive-glass model. The model predictions are found to be in qualitative agreement with some experimental observations in deoxygenated high-Tc single crystals.
