摘要
Thin films of YBa2Cu3-xFexO7-y (0 less than or equal to x less than or equal to 0.2) were made by pulsed-laser deposition using different O-2 pressures and annealing times. Their microwave absorption was measured and shows that the preparation conditions have a profound effect on the surface resistance. That is, if the Fe incorporation was successful, the microwave absorption had a large peak pear T-c. Various other diagnostics such as x-ray, ac susceptibility and atomic-force microscopy have also been performed.
