YBaCuO superconducting microbridges on Si substrates made by a novel method

High-T/sub c/ superconducting microbridges of YBaCuO films were prepared on Si substrates in-situ using a novel method. By means of that method, high-T/sub c/ YBaCuO film microbridges were grown on Si substrates with Y-stabilized ZrO/sub 2/ directly, without the need of etching processes which usually degrade the superconducting properties of the films. The DC Josephson effect, and the microwave and optical response of the microbridges were investigated. The potential applications are discussed.
