Abstract
The presence of valence fluctuating redox ions such as Pb, Tl, Sb, etc can enhance the transition temperature of the new oxide superconductors. We propose the possibility of the existence of negative Hubbard parameter (U) on redox ion which results in effective negative U on apex oxygen bridging redox ion and the CuO2 planes. This enhances Tc.
