Abstract

We have measured the time-dependence of the magnetization in Ba₂Sr₂CaCu₂O_x single crystal under the zero field cooled conditions with various magnetic fields ranging from 100 Oe to 1500 Oe along C axis at different temperatures ranging from 15K to 35K. The magnetic moment decays logarithmically with time. The decay curves have been fitted with a nonlinear logarithmic function based on the Anderson-Kim thermally activated flux creep model. We have obtained the relation between the fitting parameters and the parameters provided by the Anderson-Kim model. It is believed that our experimental results agree with the predictions made by the theoretical model.
