| Abstract: | A novel method of testing high-Tc superconducting (HTS) films by means of a slotline ring-like resonator is presented. This method does not require any metallic contact with the HTS films and ensures that the tests have quick turnaround times. Small samples can be tested very easily. The resonator circuit used has been studied analytically using Sonnet Inc.'s em software. The parameters of the HTS films are obtained by fitting the theoretical results to the experimental ones. YBa2Cu3O7-δ films on LaAlO3 have been tested and the theoretical and experimental results are presented and compared. The results match very well. This method is useful for quick screening HTS films since no patterning of the film is required |
