Abstract

As x increases in Bi4Sr3Ca3-xTmxCu4O16+y the Hall carrier density nH decreases linearly. The variation is consistent with Mott-Hubbard behavior, but in conflict with band-structure results which ignore correlations. We find that the variation of Tc vs nH is nonmonotonic. The source of the large carrier population (0.4/Cu) in the undoped (x=0) compound is discussed.
