Abstract

The flux creep process in a c-axis Bi₂Sr₂CaCu₂O_8+δ thin film was investigated at different temperatures and applied fields using Kim-Anderson approach. The peaked behavior shown in the magnetoresistance profile was attributed to the competing mechanisms of flux motion and sample-intrinsic transition near T_c. Within the temperature range where the competition occurs, U increases with temperature and consequently a decrease in the superconducting volume corresponds to a decrease in the flux creep. Moreover, the flux creep potential barrier varies with applied current I at all temperatures consistent with the Anderson-Kim model.
