摘要：

We report the zero-field-cooled magnetic relaxation and thermal activation energy in various YBa2Cu(3-x)Fe(x)O7 single crystals. No subgranularity effects were observed in our single crystals. The phenomenon of giant flux creep is evident in these systems. The magnetic relaxation rate dM/d(lnt) is strongly dependent on temperature and applied magnetic field. We utilize the Anderson-Kim thermally activated flux-creep model to analyze these systems.
