摘要：

A modified vortex glass correlation length is introduced to give a consistent description of the field and temperature dependence of the resistivity in the vortex liquid regime of high-T-c superconductors. The proposed model explicitly takes into account both thermal energy and a characteristic mean pinning energy, U-0(B, T). We find good agreement between the model and our measurements on twinned single crystals of YBa2Cu3O7-delta sand thin film Tl2Ba2CaCu2O8+delta.
