A systematic study of the flux creep behavior has been carried out for c-axis oriented epitaxial YBa2Cu307 thin films based on the Anderson and Kim flux creep model. In a wide magnetic field (H) range (0 to 12 T) and temperature (T) range ( 10 to 82 K), the behavior of the critical current density J

Current-voltage characteristics of a-axis-and c-axis-oriented YBa2Cu3Ov\_x thin films at temperatures near the superconducting transition have been investigated, using the Kosteflitz-Thouless transition model. The voltage exhibits a power-law dependence on the current in both films. The exponent a(T
We report on the temperature, angular, and frequency dependence of the microwave magnetoabsorption of YBa2Cu307 c-axis oriented thin films. Some of the films were measured as-grown (pristine) while others were irradiated with 250 MeV Ag+ 17 ions whose fluences ranged from 0.5 to 10 ร 10 ~5 m -2. By
