The film was deposited on a lanthanum aluminate, produced from a commercial powder with a nominal composition Bi1.8Pb0.4Sr2CaCu2Ox, was thermally treated by a domestic microwave oven. The XRD analysis of the film indicated the coexistence of Bi-2212 and Bi-2223 phases and SEM images revealed that a typical superconductor plate-like morphology was formed. From the electrical characterization, performed using DC four probes technique, it was observed an onset superconducting transition temperature measured around 81K. At the current-voltage characteristics curve, a step of electric current at zero-voltage could be observed, an indicative that the tunneling Josephson °Ccurred.295-299engBPSCCO superconductor thin filmsJosephson junctionMicrowave ovenArtigo10.1590/1980-5373-MR-2015-0475S1516-14392016000200295Acesso aberto2-s2.0-84962771520S1516-14392016000200295.pdf69133512511489570000-0002-2419-2049
