|Title:||Microstructure And Superconducting Fraction In The Yba2(cu1-xmnx)3o7-δ|
de Lima O.F.
|Abstract:||In this paper we report on the normal electrical resistivity, magnetic susceptibility in the diamagnetic state and metallographic analysis for samples with compositions YBa2(Cu1-xMnx)3O7-δ. The electrical resistivity increases linearly with the Mn concentration; microstructural analysis reveals the increase of additional phases with the Mn content; and a linear decrease of the relative superconducting fraction as a function of the Mn content, at 10 and 30 K, is reported. These results differ from those in the literature, for other Cu substitutions. © 1988.|
