Abstract

The superconductivity with an onset temperature of ∼110 K and a zero resistance at T _c(offset) ≃100 K was observed under measuring current I≤1 mA in the oxide with nominal composition Bi_0.7Pb_0.3SrCaCu_1.8O_x. The sharp decrease in susceptibility around 110 K due to the Meissner effect and the magnetic levitation on a magnet at 77 K were also observed in the sample. The superconducting and magnetic properties are compared with the ones for the oxides with nominal composition BiSrCaCu_1.8O_x and BiSrCaCu₂O_x.
