3. Title:
FLUCTUATION MECHANISM OF PSEUDOGAP FORMATION IN HTSC
Authors:
K.V. Mitsen, O.M. Ivanenko.



Abstract:
The mechanism of the appearance of a "pseudogap" in HTSC, responsible for the anomalous properties of these compounds, is considered in the framework of the model involving the interaction of electrons with negative U centers (NUC). The "pseudogap" in this model is shown to have a superconducting nature and to occur at a temperature T* > Tc in small nonpercolating clusters as a result of large fluctuations of NUC occupancy. The dependence of the temperature T* of pseudogap occurrence on doping for the HTSC YBa2Cu306+5 is calculated.
