| Abstract: | The pseudogap phenomenon in the cuprates can be explained by an intrinsic inhomogeneity of the samples. At temperatures above the superconducting resistive transition but below the temperature at which the pseudogap disappears, the sample contains superconducting islands embedded in a normal matrix. As a result, the normal resistance coexists with the gap structure, and there is a splitting of the resistive and Meissner transitions. |
