published as Solid State Communications 119 (2001) 271-280 · Review article and speculation. To appear in a special issue of Solid State Communications on MESOSPIN. New version includes fresh experimental evidence in support of charge melting between stripe domains (thanks to V. Kiryukhin -- see sentence and two new references added at end of section 4.2)

Self-organisation requires a multi-component system. In turn, a multi-component system requires that there exist conditions in which more than one component is robust enough to survive. This is the case in the manganites because the free energies of surprisingly dissimilar competing states can be similar -- even in continuous systems that are chemically homogeneous. Here we describe the basic physics of the manganites and the nature of the competing phases. Using Landau theory we speculate on the exotic textures that may be created on a mesoscopic length scale of several unit cells.
