Nanoscale Phase Separation in CMR Materials
Elbio Dagotto, Florida State
In recent years, evidence of intrinsic nano-scale inhomogeneities in
manganites has been gathered by dozens of experimental groups. Theoretical
developments independently arrived to similar conclusions and provided a
tentative unifying framework to understand the colossal magnetoresistance
phenomenon as caused by these inhomogeneities. The status of this active
field of research will be reviewed . The general aspects of the problem
will be discussed, including extensions to cuprates in the underdoped regime
where coexisting superconducting and antiferromagnetic clusters could be
