✦ Synopsis

The magnetoresistivity of Ag plays an important role in determining the stability and quench propagation behaviour of Ag-clad Bi-Pb-Sr-Ca-Cu-0 composite conductors. The magnetoresistivity of a silver tape that was co-processed with Bi,,4Pb,,.sSr2Ca2 Cu,O, has been measured from 4.2 K to 150 K in magnetic fields up to 20 T. The resistivity dependence on the magnetic field orientation was also studied at 4.2 K. It has been found that impurities introduced from the oxide core during heat treatment cause a significant increase in the resistivity over the entire temperature range.
