By observing the time decay of the AC susceptibility after an external field is removed from the sample, we have been able to determine the temperature dependence of the pinning energies in several oxygen deficient samples of YBCO. The time scale of the measurements extended from 100 ms to 2000 s an

In collective pinning theory, vortex pinning energy, U, is a key parameter in describing thermally activated flux motion, but it is a function of the critical current density J c , glassy exponent l and pinning energy U 0 , under the base of Griessenร•s and our groupร•s methods of obtaining J c and l,
