dc.description.abstractUsing a microstrip resonator technique, the magnetic field dependence of the surface impedance Zs=Rs+jXs, where Rs is the surface resistance and Xs the surface reactance, of superconducting YBa2Cu3O7-d thin films has been measured at a frequency of 1.1 GHz and at different temperatures. The anomalous microwave response, where Rs decreases in the presence of low dc magnetic fields, has been observed for all the samples under test at different temperatures. The anomalous microwave effect is found to be stronger at higher temperatures. The threshold field H*, at which the surface resistance show a minimum, decreases with temperature and it is governed by the competition between the anomalous effect at low fields and the vortex mechanism at high fields. © 2001 Elsevier Science B.V.
