抄録

Temperature dependence of current-voltage characteristics of Y-Ba-Cu-O thin films is studied experimentally. The observed results are analyzed with the flux creep model, and good agreement is obtained between the theory and the experiment. Using the flux creep model, the pinning potential, U, is obtained as U(T=0)≳77 meV for thin films with jc(T=0)≳2·107A/cm2. The temperature dependence of U is also obtained, and the result is discussed based on the pinning theory.
