Abstract
We have measured the resistivity of the Ag-Bi2Sr1.8Ca1.2Cu2O y composite system with Ag volume fraction p Ag ranging from 0.00 to 1.00. We find, for the samples with p Ag0.6, no zero-resistivity state is observed. The variation of the room-temperature resistivity with p Ag indicates a three-dimensional percolating Ag matrix occurring at p Ag≈0.17.Keywords
