AbstractThe activation energy U0 has been measured for melt-textured YBa2Cu3O7 samples at low magnetic induction Bc. The data indicate that U0 has a nearly linear temperature dependence in a certain temperature regime (1060 K) and is insensitive to magnetic induction. In terms of the collective-pinning ideas and taking into account the modification due to the thermal fluctuation of the flux-line lattice, we propose a possible theoretical explanation. Meanwhile, the critical current Jc, which depends upon the magnetic induction B as Jc1/ B, was obtained. © 1991 The American Physical Society.
