title = "Comparison of spin-polaron models of high-Tc superconductivity",
abstract = "Two spin-polaron models for high-Tc superconductivity are summarized and their similarities and differences discussed. In one model the Cu3+(d8) state plays a predominant role while in the other the Cu2+(d9) state is required. The importance of this difference is emphasized and extensive evidence supporting the d9 configuration is reviewed.",
