Abstract
To investigate vortex dynamics in Bi2Sr2CaCu2O8+y singlecrystalline thin films with regular holes array, we have already studied the vortex-flow resistance in various samples which have triangular, square, and randomly distributed holes arrays. A matching effect has been observed in the vortex-flow resistance in samples with the regular holes arrays. In addition to them, we measured the vortex-flow resistance, the critical current, and I-V characteristics in a sample with a regular surface structure of â¼30Â nm depth. It is found that even that kind of the small surface structure induces the remarkable matching effect in the vortex liquid as well as the vortex solid.
