Impact of SnF2 Addition on AC Susceptibility and Electrical Properties of Bi1.6Pb0.4Sr2CaCu2O8 Superconductor

The effect of SnF2 addition on the superconducting properties of Bi1.6Pb0.4Sr2CaCu2O8 (SnF2)x with x = 0-1.0 wt. % is reported. All samples were prepared by the solid-state reaction route. The powder X-ray diffraction (XRD) patterns revealed a single Bi-2212 phase for all samples. Scanning electron...
