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 a pronounced hysteresis here. At low bias current densities, j(b) < 10 A/cm2, an applied field stimulates the photoresponse, while for j(b) > 100 A/cm2 the photoresponse is depressed. All changes have occured by a field of B < 50 mT: for higher fields the photoresponse remains constant. This dependence is interpreted to arise from micrometre sized grain boundary junctions with a strongly inhomogenous critical current distribution on a sub-nanometre scale.
