We report the application of a phenomenological model for the microwave surface<br />
impedance in high temperature superconducting films. This model is based on the<br />
modified two-fluid model, in which the real and imaginary parts of the surface<br />
impedance use the modelling parameter γ. This is responsible for the superconducting<br />
and normal charge carrier density and is used for the description of the temperature<br />
dependence of the London penetration depth λL(T) including λL(0). The relaxation time<br />
model also uses the γ parameter in combination with the residual resistance parameter α.<br />
The parameter δ 1
