Abstract :
The magnetic properties of YBCO(123) highly oriented thin films with different oxygen-contents were analyzed in the low magnetic field region. A decreasing of the oxygen content shifted the irreversibility line to lower temperatures and decreased the activation energy. The Tirr(H) data for all the samples fitted well to a de Almeida-Thoules (AT)-like power law.
