Abstract:
Thin films of YBa/sub 2/Cu/sub 3-x/Fe/sub x/O/sub 7-y/ (0/spl les/x/spl les/0.2) were made by pulsed laser deposition using different O/sub 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 near T/sub c/. Various other diagnostics such as X-ray, ac susceptibility and atomic-force microscopy have also been performed.<>
