Abstract
We evaluate the frequency dependence of the nonlinear response in High Temperature Superconductor YBa2Cu3O7-x thin films by simultaneously measuring the nonlinear intermodulation products and harmonic generation in broadband superconducting transmission lines at 76 K. The frequencies of the two-tone incident signal are set to produce spurious signals from 1 GHz to 21 GHz. We extract a nonlinear term by applying a model of spurious signal generation in superconducting transmission lines to our measurement results. We find that this nonlinear term follows a linear dependence on frequency, indicating a dominant contribution of the nonlinear inductance over the nonlinear resistance , (), for the superconducting nonlinear response.Citation
