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 GriessenΓs and our groupΓs methods of obtaining J c and l,
The irreversibility line for a melt-textured YBa2Cu30 7\_ ~ (YBCO) sample was determined in two orientations of the field H relative to the sample &axis. In both orientations we obtain good fits using a melting equation with quantum correction to describe the Abrikosov lattice melting. The scaling a
