摘要：

A new theoretical explanation is given for the superconducting state in copper oxides. The key feature of the state is the following. A coherent motion of itinerant holes from low-spin to high-spin states in the presence of a relatively long-range antiferromagnetic ordering of the Cu localized spins creates a superconducting state. Based on this state, it is suggested that the attractive interaction between two holes in different energy bands with the same dispersion mediated by Jahn-Teller-type optic phonons is primarily responsible for superconductivity.
