| Oxides of manganese have received considerable attention lately, mainly because of the colossal magnetoresistance they exhibit. After a careful interpretation of the large body of available experimental results, the paramount importance of intrinsic inhomogeneities to the understanding of these materials, can no longer be ignored. A scenario, based on the competition between different ordered phases which are mixed by the intrinsic disorder, is proposed. Several quantities that follow from this scenario can be evaluated and are found to correspond to experiments. |
