Abstract
Epitaxial YBa/sub 2/Cu/sub 3/O/sub 7/ c-axis in-plane thin films and YBCO/PrBCO superlattices have been grown on single-crystal [100] and [110] SrTiO/sub 3/ substrates by high-pressure DC sputtering. The orientation of the deposited films is a function of the deposition temperature, T/sub s/. Preliminary studies of the dissipative behavior of the flux line system in the mixed state of YBCO thin films on [110] SrTiO/sub 3/ substrates were performed. Dissipation processes in both Lorentz force free and Lorentz force configurations are discussed in terms of flux dynamics under the influence of the strong pinning potential intrinsic to the layered structure. Preliminary results for a modulated structure composed of layers of YBCO and insulating PrBCO in a-axis orientation and for the first time [110]-oriented YBCO/PrBCO superlattices are presented.ETX
