| 中文摘要 | The resistive transitions of ultrathin YBa2Cu3O7-delta (YBCO) films with thicknesses 75 and 200 Angstrom were studied under magnetic fields. For the 75 Angstrom film under a 5 T parallel magnetic field (H parallel to ab-plane), no broadening of the resistive transition occurred. In the perpendicular magnetic field (H perpendicular to ab-plane), the broadening of the resistive transition of the 75 Angstrom film is larger than that of the 200 Angstrom thick film. The flux activation energy U was found to be linearly dependent on the temperature and logarithmically dependent on the magnetic field for both 75 and 200 Angstrom films, which means the two samples have a two-dimensional vortex lattice. Furthermore, the activation energy U also increased with the film thickness, indicating that the magnetic correlation length in the c-axis direction l(c) is larger than the 200 Angstrom for bulk YBCO. |
