Abstract:YBa 2 Cu 3 O 7 -δ -CuO composites with CuO particle contents of 0.5, 1.0, 2.0, 5.0, 10, 15, 20, and 24% were produced via arc plasma synthesis. Their magnetic properties were analyzed in the context of the expanded critical state model. In comparison with a reference sample, the critical current intragranular density increased in composites with CuO concentrations of 0.5, 1, 20, and 24%. The mechanisms of the influence of nanodopants on the change in the critical current density at various volume contents of n… Show more
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.
