Abstract

The Josephson photoresponse of granular high-T_c superconductor films to pulsed far infrared laser radiation has been investigated in magnetic fields of up to 3T. Its value is strongly influenced by fields less than 50 mT and shows hysteresis here, while no further changes occur for larger fields. It is shown that the field dependence directly yields information about the properties of intergrain weak links. These are found to have a strongly inhomogeneous critical current distribution.
