High-temperature superconducting films on flexible substrates for flux transformers

The physical basis of the fabrication of the third generation of high-temperature superconducting wires on quartz substrates

“…TECHNOLOGY OF HTSC SAMPLES FABRICATION The works [12][13][14][15] showed that preparation of long dimensional crystalline whisker substrates that preserve their facetted structure along lengths that are far longer than 1 cm is a task that is practically insolu ble in a reasonable time. Transition to long dielectric substrates that are made of cheap quartz optic fiber seem more promising to us; however, this requires the development of the technology for the production of high quality HTSC films on amorphous quartz whis ker substrates.…”

“…In this connection, it is necessary to form a buffer system between the substrate and the HTSC film to solve these problems. For these purposes, based on the pre vious experience with the HTSC ribbons of the second generation, we chose such materials as zirconium dioxide stabilized by yttrium oxide (YSZ) to prevent the formation of oxides and cerium dioxide to adjust the crystal lattices to the HTSC film [12][13][14].…”
