Abstract :
The samples of nominal composition Bi1.6Pb0.4Sr2Ca3Cu4 O12-xFx consist of α, β, γ, and δ-modifications of phase 2234. We observed the superconducting transition in the temperature region 110-132 K for samples with z⩽0.25. The possible model of creating superconducting state in Bi 1.6Pb0.4Sr2Ca3Cu4 O12-xFx samples is proposed
