Original Paper


The excess conductivity and magnetoconductivity of (NiO)x(Bi,Pb)-2223 were analyzed using the Aslamazov and Larkin (AL model) in order to obtain the coherence lengths ξab(0), ξc(0) at 0 K and the anisotropic parameter Γ. Both ξab(0) and ξc(0) values increase with the addition of NiO nanoparticles The anisotropic parameter values Γ in this study are less than those reported due to the polycrystalline nature of these samples.
