The influence of many-body interaction on the oxygen of the Cu-O plane in Y-Ba-Cu-O superconductors
Description
The oxygen ordering in the Cu-O plane of YBa2Cu3O7-y is investigated by introducing three-body interaction (TBI) based on the two-dimensional Ising model with the asymmetric next nearest neighbor interaction. The correlation of two neighbor Cu-O chains is discussed and phase diagrams are calculated by application of the cluster variation method (CVM). The double-cell structure at high temperature can be stabilized by the TBI. The average of the pair probabilities along the Cu-O chains shows a smooth plateau in the range of 0.3 < y < 0.53, and is similar to the dependence of Tc and room temperature resistivity on oxygen content
