Abstract

The magnetic field dependent microwave power loss in thin films of $YBa_2Cu_3O_{7-\delta}$ is analysed using the technique of non-resonant microwave absorption. The loss is correlated to the surface quality, specifically to the granularity of the film as determined by scanning electron microscopy and atomic force microscopy. We also observe that a granular surface is sensitive to degradation under aqueous attacks.
