摘要
The pseudogap state is due to an inhomogeneous structure of the compound and is described by percolation theory. The Meissner and resistive transitions occur at different critical temperatures. The "giant" proximity effect and the impact of an external pressure are analyzed. (C) 2004 Elsevier B.V. All rights reserved.
