Describes giant magnetic vortex precursors above Tc

Highlights role of background inhomogeneities

Abstract

The self-organized dopant percolative filamentary model, entirely orbital in character (no spins), is strongly influenced by background (in)homogeneities. In the high temperature superconductive (HTSC) cuprates, pseudogap regions produce novel percolative features in phase diagrams. The model is especially successful in describing the appearance of giant magnetic vortex "precursive" effects at temperatures ~2 Tc far above the superconductive transition temperature Tc.
