Abstract
The oxygenation process of the GdBa2Cu3O(6+y) thin films mas investiga ted by resistivity measurements in the temperature interval 650-1050 K and oxygen pressure 1 mbar. An iteration procedure is proposed for ca lculating the diffusion relaxation times from the curves of resistance decay with time. All samples showed a linear Arrhenius plot with an a ctivation energy E-0 close to 1.5 eV. The diffusion resulted concentra tion independent for y = 0.4-0.9.
