Description

Granular Al films have been measured in a microwave cavity at 9.4 GHz together with their dc resistance, R(T). The change in resonant frequency is proportional to the number of superconducting electron pairs which is finite above the temperature T/sub c/ /sup rho/, where R(T)approx. =0. Microwave loss has been identified which appears to be specific to granular materials and vanishes only well below T/sub c/ /sup rho/. This is shown to be due to normal conduction between grains, which upon cooling becomes progressively more Josephson-like
