Abstract

The effects of nano-sized PbO (10-30 nm) addition on the excess conductivity of YBa2Cu3 O7-δhave been studied. Excess conductivity is the fluctuations in conductivity due to the interaction of normal electrons with the Cooper pairs near the critical temperature, Tc. Samples with starting composition YBa2Cu3O7-δ(PbO)xfor x = 0.00-0.45 weight percent (wt. %) were prepared using the solid state reaction method. Superconducting fluctuations and excess conductivity were analyzed using the Aslamazov-Larkin (AL) theory to determine the conductivity dimensions λ. The Lawrence-Donaich (LD) theory was used to determine the coherence length ξc(0), Josephson coupling J, and the anisotropy γ = (ξab(0)/ξc(0)). The onset transition temperature, Tc onsetwas highest (Tc onset= 94 K) for the sample with x = 0.35. Conductivity analysis showed that nano-sized PbO induced transition from 2 dimensional to 3 dimensional conductivity with the highest transition temperature T2D-3Din the x = 0.20 sample. The Lawrence-Donaich model showed the longest coherence length ξc(0) and lowest anisotropy for the x = 0.25 sample. This sample also showed the highest Josephson coupling, J = 0.296. The two possible effects of nanosized PbO addition in YBa2Cu3O7-δis the formation of non-superconducting regions and the improved inter-grains connectivity enhanced the superconducting properties.
