Abstract
Superconducting properties and surface resistance, Rs, of YBa2Cu3O7-y strip lines prepared by the screen printing were investigated. The Tc of these strip lines with and without Ag2O and Ag additions was almost the same. However, Jc values increased with increasing the addition of Ag and Ag2O. The Rs values of these strip lines in superconducting state decreased with increasing the addition of Ag and Ag2O, and the optimum addition was about 10-15wt.%. The lowest values of Rs were about 15mΩ at 60K. The Rs values were proportional to frequency f1, in contradiction to f2 dependence expected from the two-fluid model.
