摘要：

We have investigated the nature of the in-situ growth of c-axis normal YBa2Cu3O7 thin films on non-lattice-matched, vicinal, and polycrystalline MgO substrates, and on buffer layers of MgO. We find that the preparation of the MgO surface determines the structural and transport properties of the films. In particular, we are able to reproducibly grow films exhibiting either weak link behavior of very high critical current densities. We will discuss the variation of the thin film microstructure, oxygen content, and superconductive properties with the changes in the thin film crystal structure that result from the different growth situations.
