Description
The high Tc superconductivity of the oxygen deficient perovskite Y1Ba2Cu3O7 has a closed relation to the ordering distribution of the cations with various valencies and the oxygen vacancies in this structure. The special electronic structure related to such ordering distribution leads to the phonon softening and the excitonic mechanism for superconducting pairing. These effects provide a physical model for understanding the high Tc superconductivity in this material
