We would also like to thank Nicole Bontemps for an illuminating discussion on the possible origins of the small linear term in λ ( T ). This work was partially supported by the Israel National Science Foundation, by the Heinrich Hertz-Minerva-center for High Temperature Superconductivity, and by the Oren Family chair of Experimental Solid State Physics.

N2 - The parallel plate resonator method has been used for measuring high quality YBa2Cu3O7-x (YBCO) thin films. The surface resistance and the real part of the conductivity show a non-monotonic behaviour with a broad peak around 45 K. The penetration depth and the real part of the conductivity vary linearly at low temperatures. The lowest penetration depth linear fitting has a slope value of 2.2 to 2.5 angstrom/K up to 20 K which is lower than previous measurements on YBCO single crystals. An interpretation of this smaller slope in terms of the generally accepted d-wave order parameter symmetry presents difficulties.
