Abstract
Abstract Manganese oxides (manganites) exhibit magnetic and transport properties broadly recognized as determined by intrinsic inhomogeneities, long-range interactions and fractality. Whereas first-principle approaches, and even multi-parameter phenomenological models, fail to fully describe different experimental aspects, we propose that the most adequate phenomenological tool to approach these materials is the Tsallis non-extensive statistics. In this paper we present various compelling experimental results obtained in different systems which, along a magnetic model based on Tsallis statistics, support our proposal.
