The study of the spontaneous formation of nanostructures in single crystals is rapidly developing into a dominant field of research in the subject area known as strongly correlated electrons. The structures appear to originate in the competition of phases. This book addresses nanoscale phase separation, focusing on the manganese oxides with colossal magnetoresistance (CMR). The text argues that nanostructures are at the heart of the CMR phenomenon. Other compounds are also addressed, such as high-temperature superconductors, where similar nanostructures exist. Brief contributions by distinguished researchers are also included. The book contains updated information directed at experts, both theorists and experimentalists. Beginning graduate students or postdocs will also benefit from the introductory material of the early chapters, and the book can be used as a reference for an advanced graduate course.Careful studies in one dimension have been carried out, but, in higher dimensions, only some regions of parameter space have been analyzed in detail. In addition, most of the reported results are for the so-called aquot;non cooperativeaquot; phonons, while the phase diagram of the more ... been calculated with the Monte Carlo technique, including the spin and orbital structure factors S(q) and T(q), respectively.
