Abstract

An anomalous optical response was observed in YBa2Cu3O7-x thin films showing percolative behavior in the superconducting transitions. Despite the fact that the temperature derivative of the resistance had increased considerably, no pronounced increase of optical response was found in the high resistivity regime of the transition. This nonbolometric response is likely related to inhomogeneities in superconducting properties of the films, but its nature is not well understood.
