Josephson junctions and SQUIDs on 36.8" SrTi03 bicrystal substrates were prepared from epitaxial Bi2Sr2Ca2Cu3010+8 thin films with critical temperatures around 95K. The current-voltage characteristics are well described by the resistively and capacitively shunted junction model. I,R, products of 50pV at 77K and 0.7mV at 4.2K have been reached. The I,(B) dependence is symmetric to B = 0 with an I, suppression of 90% in the first minimum. Nevertheless it turns out, that the junctions are inhomogeneous on a pm scale. SQUID modulations observed at 78K indicate a flux-voltage transfer function of 2.7pV/ao at this temperature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
