Abstract

Electrical and magnetic properties of the superconducting oxides with nominal composition (Bi_0.7 Pb_0.3) ₂Sr ₂Ca₂ Cu₃ O_x prepared from polymeric precursors have been investigated. Superconducting transition with zero-resistance temperature at T=108 K was achieved for a sample sintered at 840 °C under a low oxygen pressure. The critical current density at 77 K in a zero magnetic field is ∼400 A/cm², which is much higher than that of the Pb-free sample. Variations of the superconducting transition temperature, the critical current density, and magnetic properties with heat treatment time are discussed in connection with the structural properties.
