Abstract

We have studied nonlinear, power-dependent, behavior of high temperature superconducting thin films, transmission lines, and resonators. Here we present measurements of a material-dependent parameter, the scaling current density J0, which represents the influence of a current-dependent penetration depth on harmonic generation and intermodulations products. Four different measurement techniques were employed, and we show excellent agreement between them. The values of J0 are typically greateer than 107 A/cm2 at 76 K.
