Excess Conductivity and Magnetoconductivity Analysis of (NiO)x (Bi,Pb)-2223 Superconducting Phase

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 xi(ab)(0), xi(c)(0) at 0 K and the anisotropic parameter Gamma. Both xi(ab)(0) and xi(c)(0) values increase with the addition of NiO nanoparticles The anisotropic parameter values Gamma in this study are less than those reported due to the polycrystalline nature of these samples.
