摘要：

We have investigated the superconducting (SC) properties of ultra-thin YBa2Cu3O7-x layers in YBa2Cu3O7-x/PrBa2Cu3O7 superlattices in which the coupling between adjacent YBa2Cu3O7-x layers is modulated by varying thicknesses of insulating PrBa2Cu3O7. In particular, we have formulated a phenomenological model that accounts for the dependence of the YBa2Cu3O7-x transition temperature on both the thickness of and the separation between YBa2Cu3O7-x layers. The results of our analysis are compared with previous studies of conventional low-T-c thin film systems.
