Abstract

The superconducting properties of YBa2Cu3O7-y, (YBCO) depend strongly on the oxygen content, whereas the transition temperatureTcremains relatively constant for oxygen content between 6.8 and 7.0 (the “Plateau” effect) this effect has attracted considerable attention [see, e.g., D. de Fontaineet al., Nature (London)343, 544 (1990); H. Paulsenet al., Nature (London)349, 594 (1991); J. Jorgensen,Phys. Today44, No. 6, 34 (1991)]. In this letter we introduce a microscopic theory of this phenomenon.
