Using a high-resolution magneto-optical imaging technique, we study the flow of transport currents around cracks in monofilament(BiPb)2Sr2Ca2Cu2Oxcomposite conductors. Shunting through the Ag clad is directly observed. The current in the silver decays exponentially with distance from the crack as expected in a one dimensional distributed resistance model. At 77 K, the transfer length, &lgr;, is approximately 0.56 mm, implying an interface resistivity of7.5×10−8 &OHgr; cm2.This transfer length is found to increase slightly with increasing temperature. ©1997 American Institute of Physics.
