摘要：

We study the properties of a model Hamiltonian to describe conduction by holes in a lattice of 02- anions. An attractive interaction between nearest-neighbor holes with antiparallel spins exists in certain parameter regimes. The physical mechanism giving rise to this attraction is discussed. The model predicts extended s-wave superconductivity with high critical temperatures with dependence on hole density consistent with observations on oxides. © 1990 The American Physical Society.
