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 mag
The \(\mathrm{Bi}_{1.8} \mathrm{~Pb}_{0.4} \mathrm{Ca}_{2} \mathrm{Sr}_{2} \mathrm{Cu}_{3} \mathrm{O}_{y}\) superconductor is prepared by a citrate precursor method. Nitrate salts of the constituent metals are dissolved in deionized water, and citric acid and ethylene glycol are added. The \(\mathrm
