Description
The anomalies of the kinetic and thermodynamic properties of YBa2Cu3O6+x (x approx 0,9) in the normal state are interpreted as being responsible for by the oxygen ordering in the basal (001) CuOx planes. A sequence of structural transitions is proposed, and the phases are analyzed by the method of static concentration waves. It is shown that the anomalous behavior of the electric resistance, and of the relative sample longating may be connected with the effect of charge transfer
