摘要：

The phase diagram describing the ordering of oxygen atoms within the basal planes of YBa2Cu3O6+x is calculated using the Modified Cluster Field Method. Local arrangement of oxygens is analyzed and it is shown that, at all finite temperatures, the dominant pattern is "diluted chain", with alternating segments of occupied and empty oxygen sites. Average lengths of both occupied and empty segments are precisely quantified and presented as functions of temperature and oxygen content.
