摘要：

Radioactive In-111 has been incorporated into oriented thin films of YBa2Cu3O7-delta during a thermal coevaporation process. The hyperfine technique of perturbed gammagamma-angular correlation spectroscopy shows that 60% of the indium substitutes at a single site in the superconductor. We obtain spectra with reasonable statistics from 2 mCi of starting material, about 1% of which is incorporated into the film. Other methods of incorporating indium into films and bulk YBa2Cu3O7-delta have often resulted in a significant amount of indium being incorporated into impurity phases.
