Abstract We present measurements of surface impedanceZ S as a function of frequency, temperature, and rf magnetic field for high-quality epitaxial YBa2Cu3O7−x thin films using a striplineresonator technique that measures theQ of the resonator vs. input power. The results have been modeled using Ginzburg-Landau theory at moderate fields, and the Bean critical state model at high fields. Good agreement has been obtained between the model and the measurements. We also discuss the current distributions in the stripline for both low power whenZ S is linear and high power whenZ S is nonlinear.
