Using Madelung-energy considerations, Goodenough observed that all the candidate states he

Inhomogeneities in Manganites: The Case of La,,Ca,MnO,,hows the phase diagram of LCMO containing words reproduced from the experimental literature, at the temperature and hole density of those experiments. Clearly, in all the phases, including the ferromagnetic metallic one, and even at high temperatures, inhomogeneities have been unveiled. Experimental

Pseudogaps and Photoemission Experiments,ching similar relevance in manganites. In fact, a pseudogap has already been observed in theoretical investigations of models for Mn oxides, as well as in photoemission experiments in bilayer manganites. Both issues are reviewed in this chapter. Clearly, this is a fairly novel subarea of investigati

This result, if confirmed, would provide key support to the theory of manganites that is based on mixed-phase tendencies, and would rule out theories based on a gas of uncorrelated small polarons in the PI state. Work in the near future will hopeful
