摘要：
Flux creep characteristics of c-axis-oriented Bi2Sr2CaCu2Ox thin films grown by the method of electron beam evaporation of stoichiometric target and subsequent annealing have been investigated in the absence of external magnetic field. A decrease of the pinning potential with decreasing temperature is obtained from I-V curves. This result is explained by the presence of the spatially nonlinear pinning potential.
