Abstract :
Using a 5 GHz parallel plate resonator, several Gd123 thin films have been studied as a function of low microwave power and temperature. Two simple models which describe the power dependence of high temperature superconducting films are discussed. For this preliminary study, films were chosen whose microstructure appeared to be most suitable for modelling
