Abstract
Detailed electronic properties of cluster models of superconducting cuprate s have been determined by ab initio quantum chemistry. All near-degeneracy effects are included explicitly in the wave function description; A semi-qu antitative understanding of a low-dispersive 'oxygen metal' band, attenuate d by lattice vibrations, and coupled to an antiferromagnetic background in the case of the high-T-c SC materials, is generalized to also include colos sal magneto-resistance in the manganites.
