THE THEORETICAL STUDY OF SUPERCONDUCTIVITY IN OXIDE BaPb1-xBixO3
-
Abstract
A local Hamiltonian is introduced to study BaPb1-xBixO3. The usual CPA method is used to deal with the substitutional disorder effect. The superconducting Tc ~ x relation is calculated and the result is in agreement with experiments. Some remarks on the characteristics of oxide superconductivity are presented.
