Abstract
The dependence of the magnetization relaxation rate S = −d lnM/dlnt on temperature T is measured in YBa2Cu3O7 − δ samples with various oxygen concentrations. It is found that the S(T) curve changes qualitatively when oxygen deficit δ exceeds the threshold value δth = 0.37. For δ < δth (T c > 60 K, where T c is the superconducting transition temperature), function S(T) has the well-known peak at T/T c = 0.4. For δ > δth (at T c < 51 K), this peak transforms into a plateau and a new sharp peak appears at T/T c = 0.1. The threshold value δth of the oxygen deficit corresponds to the transition of the sample from the disordered state into the ordered state of oxygen vacancies. We consider the change in the shape of the S(T) curve as a macroscopic manifestation of this transition.
