Abstract

Measurements of superconducting properties, X-ray photoelectron and inverse-photoemission spectroscopy have been performed on Bi2Sr2Ca1-xGdxCu2Oy (0 less than or equal to x less than or equal to 1.0) ceramics,where the metal-insulator transition is observed at x similar to 0.6,The density of states at the Fermi level is reduced with increasing Gd ion contents at Ca sites. Annealing the samples in vacuo increases the critical temperature even at optimum hole concentration (x = 0.1). Changes in the electronic states are discussed in terms of the hole concentration.
