Abstract

Continued research on high Tc superconductors has led to the promise of a wide variety of industrial applications. To implement these applications, the availability of low-cost, long-length, and high-performance superconductor wire/tape and cable is critical. Preparation of these wires/tapes involves deposition of Ba2YCu3O6+x (Y213) film on biaxially-textured buffer/substrates using RABiTS or IBAD techniques. For a given combination of buffer layers that has been found to promote epitaxial growth of Y213, there may be unavoidable reactions at the interfaces between layers. Understanding of interfacial reactions of the Y213 phase with the buffer layers will provide information about how to control the formation of second phases. This paper summarizes our studies of the interactions of Y213 with selected coated conductor buffer materials, including SrTiO3, Gd3NbO7, LaMnO3, and CeO2.
