Abstract
Highly crystalline single phase “2122”, Bi2CaSr2Cu2O8+δ, sample with δ=0.25 has been prepared from citrate precursors with pyrolysis. Stable and bulk superconductivity with T c(onset)=99 K and T c(zero)=95 K was reproducibly detected by the magnetic susceptibility and electrical resistivity measurements, respectively.Keywords
