摘要：

Measurements of the intermodulation distortion (IMD) as a function of temperature from 1.7 K to T-c in YBa2Cu3O7-delta are presented. Films of the highest quality show an increase in IMD as the temperature decreases for temperatures below approximately 30 K. Films of lower quality do not show the increase in the temperature range measured. The increase is in qualitative agreement with that predicted by the nonlinear Meissner effect in d-wave superconductors. The temperature dependence of the measurements is compared with a new calculation of the nonlinear penetration depth.
