Influence of Zn concentration on electrical resistance of SmBa2(ZnxCu1-x 3O9-δ
Abstract
It is known that perovskite type structures (ReBa2Cu3O9-δ) exhibit superconductivity at temperatures below ≈ 90 K /1 3/. The substitution of other ions for Cu is interesting because the Cu-O interactions are probably responsible for the supercoductivity in those systems /4/. In the system Y-Ba-(Ag,Cu)-O Saito found that the gradual decrease of Tc with the increase of Ag concentration is due to the presence of the different phases /5/. In this letter we are reporting the experimental measurements of the electrical resistance of SmBa2Cu3O9-δ oxygen defect perovskites with Zn substituted for Cu.
