Abstract

Both interstitially Ag-doped Bi1.6Pb0.4Sr2Ca2Cu30y + x(wt%) Ag with x = 0.5, 1.0, 5.0, 10.0, 15.0, and substitutionally doped Bi1.6Pb0.4Sr2Ca2(Cu1-xAgx)0y with x = 0.025, 0.05, 0.10, 0.20, 0.40 systems were studied. Magnetic susceptibility Measurements indicate that both the interstitial and substitutional Ag-doping yield auch higher diaiagnetic signal for ZFC in a field of 60 0e at 5 K. At 80 K, -4πH/H was also enhanced by Ag-doping for H<200 Oe. Substitutionally Ag-doping also enhances the Magnetic critical current for x ≤ 0.2. Possible explanation was discussed.
