Samples of Bi 2-x Pb x Sr 2 Ca 2 Cu 3 O 10+d have been elaborated by use of three different methods. The first method uses a precursor obtained from CaCO 3 , SrCO 3 and CuO. In the second method the CuO is not used to obtain the precursor while the third method is without precursor. At each step of the elaboration, the samples are analyzed by means of X-ray powder diffraction. Final samples are characterized by Scanning Electron Microscopy. The three methods allows to obtain a pure Bi 2-x Pb x Sr 2 Ca 2 Cu 3 O 10+d phase. AC and DC Susceptibility measurements show the same critical temperature, T c , but different dependance temperature when the constant applied field is changed. Differences are also observed in magnetization measurements at 5 and 80 K. The results are correlated with the different granular structures obtained by the three methods.
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.
