摘要：

We have measured the temperature dependence of the critical current and the time decay of the magnetization in a Bi2Sr2CaCu2O8+x single crystal (Tc = 85 K). Jc decreases as (1-T/Tc)8. From the logarithmic magnet ic relaxation we deduced at 4.2 K a pinning energy U0 = 0.02 eV for the field applied parallel to the c axis. © 1990.
