| 中文摘要 | Properties of dilute pancake vortices on the surface of Bi2Sr2CaCu2O8+delta superconductors are investigated by measuring the field, temperature, and time dependencies of the critical current of the surface intrinsic Josephson junctions. It is found that the pinning of the surface vortices has two crossovers over the entire temperature range in the superconducting state. For temperatures below and above similar to 20 K, strong collective pinning and weaker point defect pinning are observed, respectively. Further increasing the temperature leads to the depinning of the surface vortices. We find that the depinning of the surface vortices can occur at a much lower temperature than that for the bulk vortices, depending on the surface-layer crystalline perfectness or the density of point defects that have been intentionally introduced experimentally. |
