Abstract

Multilayers of Bi2(Sr,Ca)3Cu2Ox/Bi2Sr2CuOx/Bi2(Sr,Ca)3Cu2Ox(2212/2201/2212) were fabricated by ion beam sputtering on polished (001)MgO substrates with a thin 2201 buffer layer. The buffer layers significantly improved the surface flatness of the multilayers. The multilayers grew epitaxially with a c-axis orientation normal to the substrate surface. The intermediate 2201 layers were uniform in thickness and the 2212/2201 interfaces were abrupt. The results indicate that the 2212/2201/2212 multilayers are suitable for the fabrication of high temperature superconducting Josephson junctions.
