A new method for a local study of nonlinear microwave properties of superconductors

Evgeny E. Pestov, Yury N. Nozdrin, Vladislav V. Kurin

We report a set of experimental data on local third-harmonic generation at microwave frequencies (0.5 GHz) in $YB{a}_{2}C{u}_3{O}_7$ and Nb films. For local investigations of the nonlinear…
