โœฆ Synopsis

A model for HTSC is considered where electrons in the CuO2 planes belong to two separate groups: (a) those localized on Cu atoms with single occupation due to a large Coulomb interaction; and (b) conduction electrons in bands formed from p states of oxygens with direct oxygen-oxygen overlap. A tight binding approximation spectrum for this model is constructed taking into account the copper potential, spin-orbit interaction in the oxygen atoms and oxygen--copper state hybridization considered as perturbation. Explanation of the known physical properties of HTSC in the normal state are given.

The symmetry analysis of electronic states in antiferromagnetic phase is applied to Cu02plane of High-To materials. The various allowed states are analyzed for characteristic points at the magnetic Brillouin zone boundary. The results show the way to discriminate experimentally between the two main
