| contents | Some effects of the doping α-Al2O3 nanoparticles in the transport properties ofBi1.65Pb0.35Sr2Ca2Cu3Oy ceramic superconductors M. Hernández-Wolpez I. García-Fornaris E. Govea-Alcaide R. F. Jardim P. Muné Física, Astronomía y Matemáticas (Bi Pb) 2223 doping transport properties We present a preliminary study on the effects of nano-size α-Al2O3 (40 nm) in the transport properties of Bi1.65Pb0.35Sr2Ca2Cu3Oy ((Bi,Pb)-2223) ceramic samples. The (Bi,Pb)-2223 samples were synthesized by the solid state reaction method and α-Al2O3 nanoparticles (NPs), with concentrations ranging from 0.1 to 0.7 wt. percent (% wt.), were added before the last heat treatment. All samples were characterized by means of X-rays diffraction patterns, and temperature and magnetic field dependence of the electrical resistivity, ρ(T, Ba). From the experimental ρ(T, Ba) data we extracted the critical temperature dependence of the % wt. of α-Al2O3 NPs, and by using the Arrhenius plot the effective pinning energy has been also determined. The results indicate that mostly of the transport properties are optimized for the sample doped with 0.3% wt. of α-Al2O3 NPs. 2018 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57082912005 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
